Re: Digital Orthoimagery and Lidar Acquisition
Dear Mr. Maas, Ms. Jorgenson, and Selection Committee members:
Ayres is pleased to provide this proposal for aerial digital orthoimagery and lidar services. Ayres has a long history
of services to counties and municipalities throughout the country and looks forward to bringing our expertise and
experience to the City of Bozeman on this project. Ayres has a proven track record of providing high-quality aerial imagery
and mapping in the Western U.S., and we hope this proposal exemplifies our unrivaled approach to your important
project.
We bring an experienced team of professional land surveyors, geographers, remote sensing experts, project managers,
and engineers who are accustomed to completing complex, large-scale aerial mapping projects around the country. Our
proven track record of successful aerial mapping projects, completed on time and on budget, has been a platform for our
success in this industry over the past 45 years. Our approach to developing high-accuracy lidar, imagery, and mapping
products is cost-effective and supports expedited production schedules. Ayres is very familiar with the area; we have
offices in Wyoming and Colorado and recently completed a similar project for the City of Loveland, Colorado, and are
currently performing land use and land cover mapping for the City of Bozeman. For your project we plan to have 95West
as our flight partner and KLJ Engineering and Planning as our survey partner. We understand that the City of Bozeman
is interested in acquiring updated aerial imagery and lidar, along with enhanced lidar derivatives for the 78.7 square mile
City planning boundary, and sidewalk centerlines within the City limits of 21 square miles. We understand the importance
of meeting the needs of multiple departments when designing cost-effective solutions, and we’ll certainly do the same for
the City.
It’s important to note that all the work we do for this project will occur within the United States. Our team of talented
survey staff, orthoimagery and lidar technicians, remote sensing specialists, mapping and GIS specialists have completed
thousands of square miles of orthoimagery and lidar processing and planimetric mapping in the past couple of years.
We believe our dynamic, client-focused approach will result in a successful orthoimagery and lidar project for the City of
Bozeman.

Ingenuity, Integrity, and Intelligence.
Since beginning to provide aerial imagery services in 1978,
Ayres’ Geospatial Division has completed thousands
of projects, from film-based imagery to rectification of
historical imagery to today’s digital imagery (including
data outside the visible spectrum) with advanced sensors
and processing techniques. Lidar has also long been an
area of Ayres’ expertise – in 2024, Ayres will have been
offering airborne lidar services for 20 years. Regardless
of the medium or content, Ayres’ project planning and
performance are built on two elements: selecting the
best approach for the client’s needs and problems, and
expert understanding and application of the principles of
orthophotography and photogrammetry. Ayres’ proposed
approach relies on both. For example, meeting your needs
includes working within the City’s budget and schedule
requirements; Ayres is comfortable that we will be able
to perform the necessary work for the budgeted amount
and within the City’s time frame. Furthermore, Ayres will
provide effective communication throughout the life-
cycle of the project and will be available to answer any
questions or concerns along the way.
Project Team and Key Personnel
The Ayres team is led by Ayres Associates Inc, a national
engineering and geospatial firm with a large presence in
the Rocky Mountain region. Ayres will serve as the prime
consultant, responsible for project management; direct
communication with City personnel; quality process
definition, tracking, and enforcement; project planning and
scheduling; all imagery, lidar, planimetric and hydrographic
processing; and delivery of all products.
Ayres’ project manager will be Tyler Kaebisch, a geospatial
data expert with deep experience in the western U.S. in
both private and public sector work and a reputation
for innovative approaches to aerial mapping projects.
Tyler also has extensive previous experience as a remote
sensing specialist for the USDA Forest Service, the US
Bureau of Reclamation, and Minnesota DNR.
Ayres has over 60 people in its Geospatial Division.
Approximately half of these are in the Aerial Mapping
group, and include GISPs, certified photogrammetrists,
and certified mapping scientists. Many of them have
worked on the Bozeman Land Use/Land Cover project.
This means Ayres has the knowledge, capacity and broad
expertise to complete the project on-time and with
excellent quality.
Most of the remaining personnel within Ayres’ Geospatial
Division are land surveyors. Ayres holds Montana land
survey licensure at the individual and firm levels. This
means that we are qualified to provide expert project
management for the survey portion of this project.
KLJ, a national engineering firm with four locations
in Montana, including Bozeman, will serve as our
subconsultant responsible for survey control and aerial
control targeting. They have provided similar services
on other Ayres projects in the past, including the City of
Bozeman’s Land Use/Land Cover project and the Montana
DOT’s Bridge Scour Study. Justin Stefanik, the survey lead
for KLJ, has spent his entire career in Montana and has
worked in Bozeman.
95West of Grand Forks, North Dakota, will perform
aerial lidar and imagery data acquisition. Through its
predecessor firm, KBM Geospatial, 95West has been
offering aerial data acquisition for nearly 60 years. They
specialize in simultaneous acquisition of lidar and imagery
and performed precisely that service as a subconsultant
to Ayres for the Rapid City (South Dakota) MPO project
performed in 2023. Their experience and familiarity with
working in the western U.S. makes them an ideal partner
for the Bozeman project. Miles Strain, the project lead for
95West, is well known in the aerial mapping industry and
has led projects for municipalities throughout the Upper
Midwest and West
Project Understanding and Overview
The City requires updated aerial imagery and lidar along
with planimetric and hydrographic data to support the
operation of various City departments as well as making
available a common, accurate set of geospatial data to
businesses and members of the public. As a fast-growing
community in the Rocky Mountain region, Bozeman is
subject to continuous change created by human and
natural forces. For example, in the past 12 months, Ayres
has identified 14 new subdivision plats recorded with
Gallatin County. Developed areas, drainage, the street
network, and land cover are all changing, and the City
government and the community require current, accurate
data to inform plans and budgeting, to assess and manage
growth, and to best display the attractions of Bozeman to
businesses, travelers, and prospective residents.
A) EXECUTIVE SUMMARY
5AYRES | DIGITAL ORTHOIMAGERY AND LIDAR ACQUISITION | CITY OF BOZEMAN, MT
Ingenuity, Integrity, and Intelligence.
In the Request for Proposal, the City has listed several
government functions that the data created under this
contract will support. Ayres understands the benefits that
will be gained by these groups, including:
• Regulatory: confirm and quantify compliance or
non-compliance with regulations and permits such as
building height, vegetation or other encroachments,
impervious surfaces, setbacks from water or roadways,
and zoning.• Land Management: identify conflicting uses; use
landform and hydrography data to predict fire and
flood risk and behavior; assess appropriateness of land
for use restrictions, reservation, or withdrawal; and
support acquisition and sale of properties.• Planning: assess transportation system and service
changes needed due to planned development,
imagery and data for grant application support,
multimodal transportation planning, parking analysis,
update land use plan, route and time analyses,
determine viewsheds and the impact of new
construction.• Engineering: high-level design, maintenance planning
and estimating, supporting data for proposers and
bidders, drainage around and within projects.
Ayres proposes to provide 3-inch pixel resolution, 4-band
digital orthoimagery collected simultaneously with QL1
lidar for the 78.7 square mile project area defined by the
City. 3D building footprints, 2D sidewalk centerlines, 1-foot
contours and hydrographic data will be produced from
the newly acquired lidar and imagery. The lidar-derived
DEM, Hydro-enforced DEM, DTM, and Hillshade layers
will be produced at a 1-foot pixel resolution. Double lined
hydro-breaklines will be created for streams greater than 2
meters wide and ponded water greater than ¼ acre in size.
A culvert and bridge breakline dataset will be created as
part of the hydro-breaklines process, which will allow for a
streamlined Elevation Derived Hydrography (EDH) stream
centerline network to be created for the project area.
The imagery and lidar will be collected under leaf-off, snow-
free conditions when the sun angle is at least 45 degrees
above the horizon. Using a minimum sun angle of 45
degrees rather than the RFP’s requirement of 40 degrees
will both improve image quality by reducing shadows
and will save time and money by eliminating the need
to organize flights to have a larger minimum sun angle
in those areas of the city where tall trees, buildings, or
steeper terrain occur. The imagery will meet National Map
Accuracy standards for 1” = 50’ mapping throughout the
project. The QL1 lidar will meet a vertical accuracy of 10cm
RMSEz on hard surfaces.
To meet these accuracy standards, all survey control will
be established by KLJ, using existing control locations to
the maximum extent possible. KLJ will confirm that all
existing control is still acceptable for use, and will create
new control points if it is not. KLJ will also establish
additional control points as directed by Ayres to meet
the promised accuracy across the entire project area. In
addition, KLJ will establish quality check points to be used
to verify the accuracy of the imagery and lidar. To comply
with the FEMA Guidelines and Specifications for Flood
Hazard Mapping Partners vertical accuracy assessment
procedures, KLJ will collect 30 NVA/VVA check shots to
assess the lidar vertical accuracy across terrain types.
These check points will be independent and will not be
used to perform aerotriangulation (AT) or calibration
computations.
The raw lidar data with be calibrated to the control points,
and the imagery will be orthorectified based on the
control points and a lidar derived DEM surface. Lidar will
be classified to the standard USGS base specification.
After the compliance of the AT solution has been verified,
Ayres’ imagery analysts will review, and correct as
needed, each image for tone balance between adjacent
images and across the project. They will also perform
manual correction of radial displacement of bridges and
overpasses. Data will be tiled using the City’s tiling scheme
and will be created from the completed images and fully
classified lidar point cloud.
As extra enhancement, Ayres will prepare three
orthomosaic files for the City: the original source 3-inch
pixel resolution for maximum quality and accuracy, and
both 6-inch and 12-inch resolutions for ease of use for City
staff and community members. Providing mosaics at the
various resolutions will maximize the accessibility of the
mosaic to the City’s user base, allowing selection of the
most appropriate resolution based on user requirements
and their available processing and rendering capabilities.
The full list of proposed deliverables is shown in section D
of this proposal, “Scope of Project.”

Production Based in the United States
All of your work will be performed in the United States. Ayres possesses more
than enough resources to accomplish this project with skilled professionals
based in the United States. For reasons of efficient production, quality
control, and security of data about critical infrastructure, it is important that
the production is directly under the control of Ayres personnel at all times.
There remain only a few geospatial firms that have their entire production
staff within the country; Ayres is proud to be among them. Each member of
our team is dedicated to quality products and services and has a personal
stake in the satisfaction of our clients.
Experienced Staff
Ayres’ geospatial division includes certified photogrammetrists (CP)
and certified mapping specialists (CMS). In addition, all of our mapping
technicians have bachelor’s degrees in the discipline of geography and
also have training in the latest photogrammetric equipment and software.
Qualifications like these result in accurate, quality mapping products that
follow project specifications closely.
Commitment to Quality
We respect our clients and understand that success is earned through
cooperation and understanding the needs of our valued clients. Our technical
and management staff make every effort to listen to clients and prepare
mapping that meets client expectations. These efforts start at the receipt of
the RFP and continue on to final delivery – and beyond.
Project Manager
Our approach to managing your project begins
with a dedication to understanding your needs
and designing solutions that address them. Too
often firms propose technical approaches that fit
the contractor better than they fit the client. We
will commit ample management resources to the
project, led by Project Manager Tyler Kaebisch.
Tyler is experienced in project management
and has a strong history of involvement in the West with over 14 years of
experience in GIS, remote sensing, and other geospatial disciplines.
As project manager, Tyler will update City of Bozeman personnel during
the course of the project to discuss pertinent project issues as needed.
Additionally, he will participate in weekly internal meetings with supervisors
to assess the status of the project and address key technical issues, thereby
maintaining high standards for product specifications and keeping the project
on track to meet the timeframe agreed upon.
8AYRES | DIGITAL ORTHOIMAGERY AND LIDAR ACQUISITION | CITY OF BOZEMAN, MT
Ingenuity, Integrity, and Intelligence.
The City of Bozeman, Montana, requires the
development of new lidar, orthoimagery, planimetric,
and hydrographic mapping. These critical datasets
will be used for land management, planning, zoning,
and engineering. The aerial imagery will meet 3-inch
resolution, and will support the development of updated
planimetric mapping of sidewalk centerlines. The lidar
data will be collected to USGS QL1 specifications,
collected at a minimum of 8 pulses per square meter
(ppsm). Lidar data will be processed to derive 1-foot
contours, building footprints, hydro and culvert
breaklines, DEM, hydro-enforced DEM, DTM and
hillshade models. Along with lidar and orthimagery
products, updated ground control survey, reports and
metadata will also be provided.
Our unique approach uses simultaneous lidar and
imagery data acquisition, which will allow for consistency
throughout all deliverables produced for this project. Our
approach will also focus the collection efforts when the
sun angle is not less than 45 degrees, throughout the
project area, which will ensure minimal shadows in areas
with tall trees or buildings greater than three stories tall.
We are confident we have a dynamic, well-planned
approach to work with the City to complete your project
successfully. We have carefully estimated the capacity
and resources needed – with a focus on maintaining
the necessary resources to complete the project on
schedule. Please note that all work for the City will
be performed within the United States by the Ayres
Associates team.
Project Management
Our approach to managing the project begins with a
dedication to understanding your needs and designing
solutions that address them. Too often, firms propose
technical approaches that fit the contractor better than
they fit the client. We will commit ample management
resources to the project, led by our project manager,
Tyler Kaebisch, who brings proven experience in
managing projects involving aerial mapping, GIS, survey,
and other geospatial disciplines.
Tyler will update the City’s personnel during the
project to discuss pertinent project issues as needed.
Additionally, he will participate in weekly internal
meetings with team supervisors to assess the status of
the project and address key technical issues, thereby
maintaining high standards for product specifications
and keeping the project on track to meet the timeframe
agreed upon.
Initial Coordination Meeting. Before project initiation,
we propose that Tyler and key staff from the City
participate in a coordination meeting. During this
meeting, we will review and refine the project schedule
and scope, discuss the acquisition conditions and
schedule, and establish a pilot project area.
Quality Assurance and Quality Control Procedures.
Ayres’ quality program defines quality as meeting client
expectations. Therefore, quality performance requires
consensus between the City and project team members
regarding the requirements of the project and design of
project strategies based on those requirements. Ayres’
quality program is dynamic and promotes continual
improvement based on feedback from our clients, from
our own project operations, and from opportunities
created by changing technologies.
Ayres and Tyler Kaebisch are ultimately responsible
for the successful completion of quality products
and services for each project. Tyler establishes the
philosophy, organization, and policy that set Ayres’
quality assurance/quality control (QA/QC) program in
place. Project managers or their designated project QA
officers implement the QA/QC program on individual
projects.
We understand that only through consistent
implementation of quality procedures can we complete
projects to our clients’ satisfaction. Ayres and our partner
95West have formal, co-developed QA/QC checks in
place and standard operating procedures designed so
that all required information is collected accurately and
that products meet or exceed project standards and
specifications.

are included in the production phases outlined in this
technical approach. Ayres will work with the City to
develop additional QA/QC procedures tailored to the
participants’ needs during this phase.
Quality Monitoring. A QA/QC team will be assigned
for each aspect of the project and will consist of
photogrammetric, mapping, survey, and GIS specialists.
The QA/QC reviews will include reviews of results and
weekly progress meetings with each project group.
Issues brought to the attention of the project manager
will be addressed immediately. The project manager
will coordinate the subcontractor’s efforts to ensure
consistent results and ensure that all procedures
implemented will be incorporated into QA/QC
documentation.
Ground Control Survey
ABGPS. Our primary method of control for the project
will be by Airborne GPS (ABGPS). All airborne cameras
and sensors used for this project will use highly accurate
geodetic-grade ABGPS systems. Location accuracy of the
ABGPS capture points will range between .02 and .05
meter.
To reduce control costs for the project, Ayres will use
a combination of ground control points and ABGPS
control. Ayres understands that we’ll be responsible for
establishing ground control points for this project. Our
survey partner, KLJ, is well known in the Montana survey
community and has extensive experience with control
networks and specifically around Bozeman. With its
professional land surveyor crew based in Bozeman, the
firm has local knowledge to give the ground survey the
attention it deserves.
Upon receiving the previously established control, KLJ
will locate and determine if they are acceptable for use in
the aerial flights. If KLJ determines any of the previously
established points are compromised it will be reset or
moved to a more ideal location. New control points will
be monumented in locations determined by Ayres as
optimal for the flight. The material used by the newly
established control will be a 2-inch aluminum cap on
a 5/8”x24” rebar, stamped with corresponding point
naming convention. Sketches, ties, and photos of the
new points will be documented for use in future flights.
Each of the previously and newly established control
points will be observed using static baselines from high
accuracy reference networks (HARN). Each mark will be
observed a minimum of two times, adjusting the height
of the instrument to eliminate errors in measurements
to the GPS unit. The static baselines will be imported in
Trimble Business Center for a least square adjustment
constrained to the HARN point coordinates. The
coordinate values of the control will be in UTM Zone 12
and Montana State Plane Coordinates, both in meters.
The resultant vectors establish the final coordinates of
the ground control points. Targets will be placed at the
center of the control point for identification during the
flight.
Photo-identifiable Targets. In addition to any
established control points, Ayres will use photo-
identifiable ground control targets; this does not require
establishing and removing panels. Photo-identifiable
targets will consist of easily distinguished ground
features such as ends of paint lines, sidewalk corners,
and corners where driveways meet road edge.
Independent Vertical Accuracy Check Shots. KLJ
will also establish additional control points as directed
by Ayres to meet the promised accuracy across the
entire project area. In addition, KLJ will establish quality
check points to be used to verify the accuracy of the
imagery and lidar. In order to comply with the FEMA
Guidelines and Specifications for Flood Hazard Mapping
Partners vertical accuracy assessment procedures, KLJ
will collect 30 NVA/VVA check shots to assess the lidar
vertical accuracy across terrain types. These check points
will be independent and will not be used to perform
aerotriangulation (AT) or calibration computations.

Ingenuity, Integrity, and Intelligence.
Aerial Imagery and Lidar Acquisition
Ayres and our flight partner in this project, 95West, propose
a simultaneous collection of lidar and imagery using
the 1560ii-s lidar sensor and the UltraCam Eagle digital
mapping camera. This system is versatile in its design,
allowing for maximum efficiency for medium- and small-
scale mapping projects. We have worked extensively with
the staff at 95West over the years on projects both large
and small, which will provide a seamless workflow for the
City of Bozeman’s project. Details concerning the imagery
and lidar acquisition technology are provided below.
Digital Aerial Imagery. The UltraCam sensor supports
aerial photogrammetric missions for the broadest range
of GIS and remote sensing applications. The complete
data acquisition system delivers small scale or large-
scale images with high-quality resolution at engineering-
scale accuracy, capable of supplying images with ground
resolutions of less than 2.5cm. Designed with break-
through technologies, the modular system consists of
state-of-the-art components, centered on frame sensor
technology, to advance all aspects of the digital workflow.
The following are features and benefits associated with
95West’s UltraCam Eagle and peripheral equipment:• Simultaneous collection of panchromatic, true color
(RGB), and near infrared bands (RGBIR).• Ground resolution of 13,080
pixels along track and 20,010
pixels across track• 12-bit radiometric resolution• FMC forward motion
compensation • Gyro-stabilized mount• Applanix 510 POS/AV system with
Litton 200 Inertial Measurement
Unit (IMU)• Computer controlled navigation
system
Lidar Specifications
We understand that the City’s current objective is to
acquire updated lidar data for this project. Ayres has
worked with tribes, municipalities, counties, utilities, and
state and federal agencies on their lidar and topographic
needs for years. Ayres’ work with the USGS 3-DEP program
includes grant writing, federal data acceptance, and
production of additional derivative products, such as
culverts and feature extraction.
Aerial lidar will be acquired simultaneously with the
orthoimagery in the Spring of 2024. Aggregate nominal
pulse density (ANPD) for the QL1 lidar acquisition will be
≥ 8 pulses per square meter (ppsm). Lidar acquisition will
be conducted by 95West when the ground is free of snow
and ice, and when the atmospheric conditions between
the aircraft and the ground are free of clouds and fog. The
calibrated lidar point cloud will support the development
of a bare earth surface model (DEM) to meet the following
vertical accuracy requirements: • RMSEz (non-vegetated) ≤ 10 cm (point cloud and
DEM). • NVA ≤ 19.6 cm at 95% confidence level (point cloud
and DEM). • VVA ≤ 30 cm at 95th percentile level (DEM only).
Lidar Sensors. Not all lidar sensors are the same. Even
when using current technology, different sensors may
provide different results. Some sensors can be flown higher
and faster, some can provide a higher pulse rate, some can
provide more returns, and some can provide less noise.
Ayres has been producing lidar data since the early 2000s,
and we dedicate significant time to understand the benefits
of each new generation of sensor on the market and modify
our project planning and production workflow to adopt the
benefits of new technologies to the appropriate projects.
Given the large size and high-density requirement for the
City of Bozeman’s project, Ayres recommends using Riegl’s
1560II. Among other benefits this system offers:
• High laser pulse repetition rate up to 800 kHz. • Unrivaled scan pattern for best point spacing on the
ground. • Innovative forward/backward looking capability for
collecting data of vertical structures.
11AYRES | DIGITAL ORTHOIMAGERY AND LIDAR ACQUISITION | CITY OF BOZEMAN, MT
Ingenuity, Integrity, and Intelligence.
• Offers highly efficient data acquisition at a wide range
of point densities. • Digitization electronics for full waveform data. • Enables Multiple-Time-Around (MTA) processing for
resolving range ambiguities automatically. • Excellent suppression of atmospheric clutter. • Integrated inertial measurement unit and GNSS
receiver.
Additionally, this sensor is capable of collecting seven or
more returns from each lidar pulse, allowing for better
penetration of vegetation, less data voids, and better data
for feature extraction. It is known to produce very little
noise in the data.
Flight Planning Quality Assurance. Ayres will take
special care in designing an optimal flight plan that will
achieve maximum coverage and efficiency for the QL1 lidar
and the 3-inch orthoimagery. Upon notice to proceed, Ayres
will present the flight plan to the City of Bozeman prior to
any flights. For the imagery acquisition, there will be a total
of 648 images over the 18 flight lines. For reference, the
proposed simultaneous QL1 lidar and the 3-inch imagery
flight plan is shown below.
Data for the geographic extents of the project will be
acquired using the correct mission profiles for the desired
final products. Proper planning of flight lines promotes the
success of this project (with minimal rework) – and proper
planning optimizes lidar performance versus cost.
Mission planning consists of several steps for proper flight
preparation. First and foremost, the project boundaries are
imported into the flight planning software. Following this,
we review available information, such as elevation data,
vegetation coverage data, and cultural feature extents
of the area. General assessments are made by certified
photogrammetrists to determine the proper lidar system
settings, such as FOV (field of view) and GSD (ground
sample distance). All lidar flight lines will be flown to ensure
no data void exists between lines.
Conditions During Acquisition. Imagery and lidar will be
collected in stable weather conditions, e.i., cloud-free, low-
moisture, leaf-off, snow-and-ice-free. Photography and lidar
will not be captured when the ground is obscured by snow,
haze, fog, dust, or cloud shadows in any one photo. Data
will not be collected until all bodies of water in the project
area are free of ice.
Flight Management System. The aircraft is guided by
a GPS-controlled flight management system. During the
mission, the crew will monitor all functions involving the
operations and guidance systems, allowing for continuous
onboard QA.
Freshwater Surface Hydrography Conditions. The
lidar collection will target low-flow discharge conditions
throughout the project area. No unusual flooding or water
inundation will be present during the acquisition. Ayres will
work closely with the City and local experts to determine
the most suitable ground conditions for the flight mission.
FAA Certification. All aircraft used in the performance
of this contract will be maintained and operated
in accordance with all regulations required by the
U.S. Department of Transportation, Federal Aviation
Administration (FAA).
Positive Control Airspace. It will be Ayres’ responsibility
to obtain all approvals necessary to ensure that required
clearances are achieved for the flight missions. When
the flight plan and location of any project area coverage
fall within positive-control airspace, the aircraft must
BOZEMAN FLIGHT PLAN
12AYRES | DIGITAL ORTHOIMAGERY AND LIDAR ACQUISITION | CITY OF BOZEMAN, MT
Ingenuity, Integrity, and Intelligence.
contain the appropriate equipment to operate in such
positive-control areas within the purview of the federal
aviation regulations. In addition to all FAA requirements,
all flights requesting clearance in the vicinity of “VIP” type
airspace with temporary flight restrictions (TFR) will notify
the contracting officer before receiving FAA clearance for
instructions.
Acquisition Date. Imagery will be flown when deciduous
foliage is under leaf-off conditions. The target flight window
will be between April 1 and April 30, 2024, or as weather
permits.
Sun Angle. The sun angle for all flights will be at least 45
degrees above horizon.
Stereoscopic Coverage. The entire area of the project will
be stereoscopically covered by successive and adjacent
overlaps of photographs within the usable portion of the
field of the lens.
Four Band Imagery. The UltraCam Eagle collects imagery
in the standard three RGB color bands, as well as a fourth
band for near infrared. Ayres will provide the City with all
four-color bands at no additional cost to the City.
Crab. Average crab for any flight line will not exceed 3
degrees. Crab will not exceed 3 degrees between any two
consecutive flights.
Tilt. Imagery collected with the optical axis of the aerial
sensor in a vertical position is desired. Tilt is angular
departure of the aerial sensor axis from a vertical line at the
instant of exposure. Tilt will not average more than 1 degree
for the entire project.
End Lap/Side Lap. The end lap will average not less than
55% or more than 65%. End lap of less than 55% or more
than 65% in one or more images will be cause for rejection.
The side lap will average 30%. Any image having side lap
less than 25% or more than 35% will be rejected.
Reflights. Lack of acceptable imagery or gaps in swaths will
be corrected by reflights, with no additional cost to the City.
All reflights will be centered on the plotted flight lines and
will be taken with the same camera system.
Image Review. Immediately upon completion of the
acquisition, the imagery will be forwarded for inspection
to our digital orthoimagery supervisor, Aaron Sale. Once
we confirm successful acquisition and image quality, the
City will be notified. If any imagery does not meet the
acceptance criteria, a reflight will be scheduled and the City
notified.
Digital Orthophotography Production
As aerial data collection missions are completed,
orthoimagery production will begin. Ayres has significant
digital orthoimagery production capability and capacity.
We invest heavily in our staff and hardware. Our production
methodology is specifically designed to consistently
produce high-quality products.
Specialists at Ayres will be responsible for all orthoimagery
production components of the project. Advancements in
production software and our investments in infrastructure
favor an increasingly aggressive schedule for the upcoming
project; we are committed to meeting the City’s schedule
expectations for this project.
Ayres has trained and experienced staff running
fully equipped Z/I Imaging digital workstations, NT
orthoimagery workstations, and dedicated image editing
stations.
We’ve designed our complementary production
methodologies to facilitate a completely digital workflow
using all Z/I hardware and software environments, resulting
in a consistent approach to orthoimagery production and a
high-quality product.
13AYRES | DIGITAL ORTHOIMAGERY AND LIDAR ACQUISITION | CITY OF BOZEMAN, MT
Ingenuity, Integrity, and Intelligence.
Analytical Aerotriangulation (AT). To maintain an
aggressive schedule, it will be critical to prepare for AT
immediately upon the successful completion of each
imagery mission. This is the first step in the orthoimagery
production process and must be completed in efficiently
for the rest of the ortho process to proceed on schedule.
Planning for sufficient capacity in this area is critical to
the project.
Several important factors will contribute to the efficient
AT processing under our approach. The first is the use of
ABGPS and IMU data, which provide image orientation
information to streamline AT production. The orientation
data significantly reduces processing time and allows us
to process large blocks of image data at a rapid rate.
AT Solution. Although orientation data will be supplied
from the IMU, we will still complete an AT solution to
verify the ABGPS and IMU data. We will prepare the
AT solution on a Z/I Imaging digital photogrammetric
workstation using Z/I Imaging ISAT software. ISAT offers a
complete softcopy aerotriangulation software suite that
includes interior orientation, point mensuration, relative
orientation, and a fully analytical simultaneous least
squares adjustment with robust error detection. ISAT
incorporates the capability to weigh control points on
an individual basis and to correct for image deformation,
atmospheric refraction, earth curvature, and lens
distortion.
Aerotriangulation QA/QC. When a block of
aerotriangulation has been completed, all reports
and supporting documentation will be examined for
compliance with project specifications. This testing will
include, at a minimum, the following:
Inspect ABGPS positions against AT-derived
exposure coordinates
Compare AT-derived coordinates of independent
QA points against ground survey
Inspect measurements, residuals, weights, RMSE
in AT listings
Verify all AT support and measurement files are
in archive
Verify metadata is complete and in proper
format
Rectification Type. We will use a cubic convolution
resampling method for all orthoimagery rectification. This
method preserves fine detail better than the common
bilinear algorithm. Our imagery specialist will take extra
caution around overpasses and bridges to ensure the
correct horizontal location of these features holds true.
Tone Balancing. Digital orthoimagery is subject to tonal
imbalances due to several factors, including source
photography (sun angle, illumination, atmospheric
conditions, and date and time of exposure), image
characteristics, and image processing. Our ortho
specialists will not only tonal balance the individual
images, but also will use tonal balancing techniques to
the project. This process will eliminate the flight line
effect and individual photo effect.
Digital Terrain Model (DTM) A newly acquired
lidar digital terrain model (DTM) will be employed to
orthorectify the imagery.
The data will be thoroughly reviewed by Aaron Sale,
our orthoimagery supervisor, and he will report any
inconsistencies to the lead lidar specialist, Adam
Campbell.
Radial Displacement. Our ortho production staff
will also manually correct radial displacement and
distortion of bridges and overpasses through a series
of pre-rectification measures and post-processing
edits. A thorough examination of these features will be
conducted during the interim and final QA/QC checks.
Mosaicking. To achieve consistent tone across the
project area and to address the overlap between tiles, we
will seamlessly mosaic the images. We will select imagery
14AYRES | DIGITAL ORTHOIMAGERY AND LIDAR ACQUISITION | CITY OF BOZEMAN, MT
Ingenuity, Integrity, and Intelligence.
in a way to use the most advantageous area of each
photo to maximize color, tone, and contrast, and at the
same time reduce building lean and “ghosting,” as well as
glare in water bodies.
Image mosaicking will be accomplished by a combination
of automated tools and manual methods. All seam
lines will be placed manually to eliminate the issues of
noticeable seam lines through buildings, bridges, and
other features. Following the completion of imagery
production, a shapefile of seam line locations will be
provided to the City.
We will use manual editing procedures to provide QA/QC
for every tile for visible seam lines in water bodies, warped
bridges, and any anomalies that may affect the accuracy
or aesthetics of the imagery. We will use photogrammetric
software products such as Z/I Imaging’s Digital Ortho-
Production Suite: ImageStation OrthoPro, PixelQue,
IRAS/c, and Digital Image Analyst.
Orthomosaics. Ayres will prepare the project wide
mosaic imagery at the original 3-inch pixel resolution for
maximum quality and accuracy. In addition to the 3-inch
mosaic, both 6-inch and 12-inch resolution orthomosaics
will be provided for ease of use for City staff and
community members. Providing mosaics at the various
resolutions will maximize the accessibility of the mosaic
to the City’s user base, allowing selection of the most
appropriate resolution based on user requirements and
their available processing and rendering capabilities. The
3-inch and 6-inch resolution mosaics will be provided as
additional deliverables at no added cost to the City.
Accuracy. Resultant orthoimagery will be 3-inch orthos
that will conform to National Map Accuracy Standards
(NMAS) for 1”=50’ scale mapping; this translates to a
horizontal accuracy of +/- 1.7 feet.
Orthoimagery Tiling Scheme. Ayres will use the City-
provided tiling scheme to deliver edge-matched, non-
overlapping tiles. The same tile scheme will be used for
the orthoimagery and the lidar. Should the City want to
use a different scheme for their 2023 project, Ayres will
work with the City to accommodate that request.
Digital Orthoimagery Pilot Projects. Early in the
imagery production phase, a pilot area consisting of
geo-referenced TIF images can be provided to the City
for review and feedback. We propose further discussion
concerning the best area for review during the project
kick-off meeting.
Coordinate System/Datum. All mapping products
associated with this project will be prepared and
delivered in both Montana State Plane NAD83 (2011)
meters, NAVD88 meters and UTM Zone 12 NAD83 (2011)
meters, or another agreed upon coordinate system.
Orthophotography Quality Control
Project manager Tyler Kaebisch will be responsible for
coordinating the final QA/QC of the orthoimagery. Our
highly trained technicians will visually scour the imagery
looking for anomalies or potential errors. If further editing
is needed, a detailed edit call report will be returned to
Ayres to perform corrections as needed. If the data meets
specifications, the orthoimagery will be prepared for the
final battery of checks.
While overseeing the QA/QC, Tyler will work with the
City to develop a check-in process for the imagery and a
method by which edit calls can be recorded. If the City
determines that the data needs further editing, Tyler
will determine what action needs to be taken in the
orthoimagery process. The Ayres team will conduct the
following QC procedures:
1. Create an overview of each deliverable and combine
the overviews to inspect overall radiometry,
geographic accuracy, and complete coverage.
2. Orthoimagery QA technicians will perform QC on
each image. QC forms will be submitted with the
Project Planning Manual.
15AYRES | DIGITAL ORTHOIMAGERY AND LIDAR ACQUISITION | CITY OF BOZEMAN, MT
Ingenuity, Integrity, and Intelligence.
A thorough inspection of every ortho image tile will be
conducted with an evaluation criteria based on:
Seamless geometry
Seamless radiometry
Appropriate dynamic range
Appropriate mean intensity
Appropriate contrast
Detection of data dropouts
Complete coverage
Appropriate resolution
Shadows, clouds, low sun angle
Bridge, overpass distortion
Lidar Data Processing
Ayres has extensive experience processing lidar data to
meet strict specifications over large areas. Our technicians
will use several software packages specifically designed for
lidar processing. These software packages include GeoCue
and the TerraSolid suite of processing components. The
GeoCue software is a database management system
for housing the lidar dataset (usually multiple gigabytes
to terabytes in size). Additionally, the GeoCue program
incorporates a thorough checklist of processing steps and
QA/QC procedures that assist the technicians in the lidar
workflow.
Hydro-flattening Breaklines. We will collect new
breaklines in a 3-D environment to support appropriate
modeling and hydro-flattening of contours along water
bodies. Whereas some geospatial firms take the approach
of using existing hydro vectors or heads-up digitized
“breaklines” as a means of cutting processing cost, our
team collects new breaklines in a 3-D environment. Our
approach will ultimately result in a much truer horizontal
and vertical position of hydrographic features and will more
accurately reflect conditions at the time of lidar acquisition.
The result will be a more accurate surface model and
cleaner contour generation across the entire project.
Hydro breaklines are collected using lidargrammetry.
This process involves manipulating the lidar data’s
intensity information to create a metrically sound stereo
environment. From this generated “imagery,” dependable
breaklines can be photogrammetrically compiled. This
capability allows us to offer high-accuracy terrain data
from lidar without supplemental aerial imagery. Breakline
polygons are formed to represent open water bodies,
including lakes, and streams. While the current USGS
3-DEP base project standards call for hydro breaklines to
be created for streams wider than 100 feet and ponded
water of two (2) acres or greater, it is important to note that
for the City of Bozeman project, we will be collecting hydro
breaklines according to the following specifications:• Double-lined breaklines for streams and ditches
greater than 2 meters wide• Water bodies (ponds, lakes, reservoirs) greater than ¼
acre in size
Additional breaklines will be collected for bridges, culverts,
and streams and ditches less than 2 meters wide for
production of a hydro-enforced DEM and Elevation Derived
Hydrography (EDH). Additional details for the below in the
Hydrographic Mapping Services sections.
Point Cloud Automated Classification. The TerraSolid
suite of software is used to automate the initial
classification of the lidar point cloud based on a set of
predetermined parameters. It is at this point that we will
refer to the ground cover research (natural and cultural
features) within the project area. This will be very useful in
determining the algorithms most appropriate for the initial
automated lidar classification. (Some algorithms/filters
recognize the ground in forests well, while others have
greater capability in urban areas.)
During this process each point is given an initial
classification based on the point’s coordinates and its
relation to its neighbors. The initial values offer a coarse
and inexact dataset but are a good starting point. It is
during this step that “overlap” points are automatically
classified (those originating from neighboring flight lines).
16AYRES | DIGITAL ORTHOIMAGERY AND LIDAR ACQUISITION | CITY OF BOZEMAN, MT
Ingenuity, Integrity, and Intelligence.
This classification is based on information gathered from
the AGPS and IMU data.
Point Cloud Manual Classification. TerraSolid is also
used for the subsequent manual classification of the lidar
points. This software permits technicians to view the point
cloud in a number of ways and within a number of contexts
provided by other available datasets such as orthos or
road centerline files. This combination of automated and
manual processes provides a cost-effective approach
to the tedious practice of point classification, while still
allowing our talented technicians to review and confirm the
results of automation.
Current USGS base specifications require delivered point
cloud in LAS v1.4 format. Classification includes: • Class 1: Processed, but unclassified • Class 2: Bare-earth ground • Class 6: Buildings (automated & manual, if necessary) • Class 7: Low noise • Class 9: Water • Class 17: Bridge decks • Class 18: High noise • Class 20: Ignored ground (breakline proximity)
Surface Models. Once the hydro-breakines and point
cloud classification are complete, Ayres will derive the
following surface models:• 1-foot pixel resolution Digital Terrain Model (DTM):
Elevation data points will be delivered as either
a regular or irregular DTM in esri geodatabase
compatible format• 1-foot pixel resolution Digital Elevation Model (DEM):
Gridded raster representation in esri geodatabase
compatible format • 1-foot pixel resolution Hillshade: Grayscale 3D
representation of the bare-earth surface in esri
geodatabase compatible format
Contours. Ayres can deliver 1-foot contours processed
from the lidar surface. After the DTM processing is
complete, our GIS technicians will generate the final
contours using Boeing-Autometric KDMS software, a
TIN-based system. The index contours, intermediate
contours, index depressions, and intermediate depressions
will be clipped to the tile boundaries. Each contour line
will be attributed with the elevation value. The contours
will then be topologically cleaned to ensure a seamless
dataset across the project area and translated to an .esri
geodatabase.
Lidar-Specific QC
Quality control of lidar is a system of routine technical
activities to measure and control the quality of the
mapping deliverables and services as they are being
performed. The QC system is designed to: • Provide routine and consistent checks to ensure data
integrity, correctness, and completeness • Identify and address errors and omissions • Document and archive inventory material and record
all QC activities
Ayres’ lidar QA/QC specialist, Adam Campbell, CMS-Lidar,
GISP; will lead the lidar QA/QC process. In that capacity,
he will work with project manager Tyler Kaebisch, to fulfill
our team’s commitment to providing quality products and
services. In his supervisory role, Adam has a number of
specific technical workflows at his disposal. The following
highlights the primary steps in a lidar QC plan:
17AYRES | DIGITAL ORTHOIMAGERY AND LIDAR ACQUISITION | CITY OF BOZEMAN, MT
Ingenuity, Integrity, and Intelligence.
a. Review mission logs and examine mission parameters
b. Vertical accuracy validation
c. Automated edit of the raw data
d. Visual inspection of data
e. QC of lidar classification
f. Systematic review of point clouds
g. Surface model verification
(a) Review Mission Logs and Parameters. The first step
in the QC process is to review the mission parameters
against the statement of work and the overall project
objectives. Once the flight specifications are confirmed, the
base station data sheets and AGPS data will be reviewed to
determine that they meet required tolerance and minimum
requirement for operation. Additionally, the raw data will be
reviewed to verify project area coverage, individual swath
overlap parameters, and appropriate point density.
(b) Vertical Accuracy Validation. Using a “Z-probe”
methodology, the lidar supervisor will compare surveyed
ground control, independent check points, and published
monuments against the lidar bare-earth surface. This
statistical test will verify that the lidar acquisition and
calibration has been completed to meet the accuracy
objective of the project.
(c) Automated Edits. This process will ensure the removal
of extraneous points and artifacts. Additionally, it will
determine that all desired features have been retained
within the dataset. Filtered and edited data are subjected
to semi-automated algorithms defined within our internal
production manuals.
(d) Visual Inspection. A series of quantitative and visual
procedures is employed to validate the accuracy and
consistency of the filtered and edited data. Importantly,
human eyes will review every square mile of the project.
A rigorous peer-to-peer system, in addition to the overall
QA/QC process, results in a substantial focus on quality
and precision.
(e) QC of Lidar Classification. After querying specific tiles
into their workspace, our technicians will begin scanning
through the tile, searching for areas where the automated
classification routine erred. They will view the datasets
from numerous angles, generate triangulated irregular
networks (TINs) or contours, and consult shaded relief
models to fully understand the data model at each point
of their analysis. Using this information and technical
experience, our technicians will detect, investigate, and
correct any areas that display anomalies – i.e., areas where
the automated classifications show weakness.
(f) Systematic Review of Point Clouds. The technicians
will systematically work their way through anomalous areas
– taking narrow swaths of data, viewing the swath from
isometric and profile viewpoints, and reclassifying each
point in accordance with their expertise. Technicians focus
on eligible classifications, which include “unclassified”
(buildings, vegetation, and other non-terrain/non-noise
features), “ground,” and “noise.” Points falling under the
“water” and “overlap” categories are weeded out effectively
during automated procedures.
(g) Surface Model Verification. After this process is
complete for the area, the technician will generate new
TINs and contours to determine that the anomaly has
been fully addressed. If it has, the technician will continue
scanning the tile for other anomalies. This procedure will
continue until the tile has been determined to meet or
exceed project specifications. At this point, the technician
will query the adjacent tile and continue working.
Planimetric Mapping Services
We understand there is a need for new planimetric
mapping features for the project area. New planimetric
mapping of Sidewalk Centerlines will be collected for the
21 square mile City Limits project area, while Building
Footprints with heights will be collected for the entire
78.7 square miles project area. Our process ensures
feature alignment is congruent with coinciding features for
provision of a seamless dataset. The final product for all
planimetric features will be consistent with National Map
Accuracy Standards for 1” = 50’ horizontal map scale.
18AYRES | DIGITAL ORTHOIMAGERY AND LIDAR ACQUISITION | CITY OF BOZEMAN, MT
Ingenuity, Integrity, and Intelligence.
Building Footprints. Ayres will collect 2D building
footprints for the entire project area derived from the
Lidar buildings classification collected for this project.
Building footprints will be digitized at the building roof
edge (drip line) for structures with a minimum size of
100’ x 100’. Buildings will be topologically structured and
delivered as 2D flattened polygons in ESRI geodatabase
format. In areas where buildings meet either pavement
edge or impervious surface features, a topology will
be run to ensure seamless line work between different
feature types. Buildings will have a maximum height
above ground as at attribute within the attribute table.
Sidewalk Centerlines. Ayres will stereo-graphically
compile all sidewalk centerlines within the City limits. All
public sidewalk centerlines will be captured. Ayres will
review any existing City polygon sidewalk inventories
to aid in identifying potential areas of change. Sidewalk
centerlines will be captured and prepared as polylines.
The mapping will be delivered in ESRI geodatabase
format.
Hydrographic Mapping Services
We understand there is a need for new hydrographic
mapping features for the project area. Updating
watercourse hydrography for the 78.7 square mile
project area will greatly benefit any potential drainage
and storm water studies the City intends to perform in
the future. In order to correctly capture all drainage and
depressions along the landscape, Ayres recommends
collecting a culvert inventory dataset from the lidar and
imagery to ensure water modeling will replicate the true
flow of water within the project area. If the City already
possesses a recent culvert inventory database, Ayres will
use it to ensure proper representation of water flow. By
using the lidar DEM surface and the culvert inventory,
a hydro-enforced DEM will be created allowing all
water conveyance features across the landscape to be
captured.
3D Hydrographic Mapping from lidar. Ayres uses
the ArcHydro toolset to derive intermediate lidar raster
products and ultimately polylines representative of
accumulated flow across the landscape. Using the hydro-
modified DEM, an interative process of creating flow
directions, contributing areas, and stream raster grids
will be generated as part of hydrography processing.
Elevation Derived Hydrography will replicate the flow of
water at a 1 : 2,400 scale.
Ayres will work with the City to determine the level of
detail needed to capture the river, streams, drainages,
and ditches within the project area. The following
hyrdographic features will be captured:
Culverts and Bridges• Breaklines will cut through culverts and bridges and
will allow water to flow from the tops of hills all the
way down through the stream network. A hydro-
enforced DEM will be produced with the lidar DEM
and culvert and bridge breakline datasets.
Ponds and Lakes• Ponded water of 1/4 acre and larger will be captured
as part of the hydrobreakline process within the
standard lidar processing deliverables.
Rivers, Streams, and Ditches• Rivers, streams, and ditches 2 meters and wider will
be captured as part of the hydrobreakline process
within the standard lidar processing deliverables.• Rivers, streams, and ditches less than 2 meters in
width will be captured as polylines with the ArcHydro
3D Hydro mapping tools.

E) RELATED EXPERIENCE
Wisconsin Regional Orthoimagery Consortium – Imagery and Lidar
The WROC is a multi-entity group whose
goal is to build and sustain a multiparticipant
program to acquire elevation data and digital
orthoimagery throughout Wisconsin for
use in tasks ranging from tax assessment
to emergency management. WROC 2020
marked the sixth time since 1995 that a
regional consortium in Wisconsin has worked
together with this goal. Ayres was selected
to manage and facilitate again for the 2025
edition.
During the 2020 cycle, 11,000 square
miles of aerial lidar and 56,000 square
miles of aerial imagery was acquired, with the
Ayres team delivering customized datasets to
more than 100 separate entities.
In 2014 and 2015, this program resulted
high-accuracy lidar for topographic
mapping in 17 counties.
The public has gained access to statewide aerial imagery coverage through this program. Over the years public and
private partners have contributed significant funds toward imagery and lidar projects in exchange for access to these
high-quality spatial datasets. Partners include utilities, electric cooperatives, tribes, municipalities, private industry, and
state and federal agencies.
Examples of diverse products within the WROC program include:
• Lidar with 1-foot and 2-foot contours for floodplain studies • Detailed planimetric mapping for GIS • Multispectral imagery for environmental analysis and forestry• 6-inch or 12-inch resolution orthoimagery for countywide projects • 3-inch resolution for municipalities • 18-inch resolution derivative regional datasets
To facilitate a cooperative approach for orthoimagery data acquisition, WROC and Ayres worked with the Wisconsin land
information community to strengthen relationships among local, regional, state, and federal entities, as well as tribes
and utilities. The program is designed to allow all participants to receive products and services tailored to their individual
geospatial needs. Participants were given a range of orthoimagery options from 3-inch up to 12-inch resolution in addition
to specialized formatting and coordinate system outputs. Customized photogrammetric and lidar services also make up
a significant part of the WROC program.
We collected countywide lidar in conjunction with new aerial
imagery. Ayres was able to use the surveyed lidar data to process the
orthoimagery to meet and exceed ASPRS Class 2 horizontal accuracy
specifications. Lidar data was also collected in conjunction with an
NSSDA survey to check its accuracy.

Bismark-Mandan MPO Orthoimagery and Lidar, 2020
The Bismarck-Mandan Metropolitan Planning
Organization (MPO) kicked off its partnership
with Ayres in 2009 to collect aerial imagery
and lidar to modernize its base mapping data.
The MPO has since acquired 6-inch imagery
and 1-foot contours derived from lidar in 2013
and 2016. In 2020, Ayres provided the MPO
with higher resolution data products, including
3-inch pixel orthos and lidar to support 1-foot
contours and high accuracy surface modeling
and change detection.
At Ayres we’re big supporters of both formal
and informal regional organizations banding together for aerial mapping services. Through programs such as this one,
we’re able to facilitate collaboration among organizations in need of similar services, which becomes a mutually beneficial
relationship. This approach is not only extremely cost effective but also
allows for the growth of standardized, high-quality geospatial datasets
across regional borders.

Schweitzer Mountain Resort Lidar, Orthoimagery, and Planimetric
Mapping 2021
Ayres was retained by Schweitzer Mountain
Properties and construction management agent
OAC services of Seattle to acquire aerial imagery
and high density lidar and to provide survey and
mapping of the Schweitzer Mountain Resort
near Sandpoint, Idaho. The 7,000-acre resort
in the rugged Selkirk Mountains of the northern
Idaho panhandle is considered to be one of the
best family-friendly ski resorts in the Pacific
Northwest.
This mapping will support the initial planning
and design stages of a 10-year expansion effort
for the resort. Ayres performed the ground
control targeting survey and acquired 3-inch
color aerial imagery and high-density 20 ppsm lidar with a simultaneous
collection aerial mission and provided our client with digital orthoimagery
including large scale laminated color wall maps, colorized lidar point
clouds, digital elevation model, contour mapping, and 50 scale planimetric
mapping of roads, buildings and other pertinent infrastructure.
City of Laramie, Wyoming, Aerial Imagery and Lidar 2017
The City of Laramie selected Ayres to provide aerial imagery, lidar, and
planimetric mapping services through a quality-based selection process
during spring 2017. The City wanted to collect a total of 97 square miles of
data that not only covered the City but also some surrounding rural areas
and a ranch property owned by the City.
The City planned to update imagery and topographic data
collected in 2009, which is widely used by City Engineering,
Planning, Streets, Utilities, Parks, and GIS Departments.
Included in the 2017 project was a combination of 3-inch and
6-inch imagery for urban and rural areas respectively, as well
as the provision of lidar for the generation of 1-foot contours
and a new surface model. The City also requested planimetric
mapping for all hydrographic features and pavement striping
throughout the project area.

City of Loveland Lidar and Orthoimagery
In the spring of 2021, Ayres was selected to provide lidar
and orthoimagery mapping services for the City of Loveland
located in southeastern Larimer County, Colorado. For this
project, Ayres used a calibrated lidar sensor and digital
photogrammetric camera for a simultaneous collection of
high-density aerial lidar and 3-inch photography to derive
orthoimagery, 1-foot contours, and a detailed surface model.
Lidar and aerial imagery were collected and processed for
70 square miles, which included the City of Loveland Growth
Management Area and the Loveland Water Storage Area.
Quality Level 1 lidar was collected at 8 pulses per square
meter, and the calibrated lidar point cloud supports a bare
earth surface model meeting a vertical accuracy of RMSEz
of <= 10 cm, and NVA of <= 19.6 cm at the 95% confidence
interval for the point cloud and digital elevation model
(DEM). The 3-inch digital orthoimagery meets ASPRS Level 2
horizontal accuracy standards of 0.7 feet RMSE, which equates
to 1.2 feet at the 95% confidence interval according to NSSDA
standards. The calibrated lidar point cloud was classified to
the USGS standardized base classification scheme. A DEM
consisting of bare-earth ground points was also derived to
support the interpolation of 1-foot interval contours to National
Map Accuracy Standards.
Additionally, Ayres complied hydro-flattened breaklines for
ponded water that is two acres or greater and double line streams that are 20-feet in width or greater, which were used in
the creation of the bare earth DEM and contours. Ayres collected all ground control survey points required to complete
this project.
Final deliverables to the City of Loveland included:
Raw and classified lidar point clouds in .Las format
A DEM surface in GeoTIFF format
1-foot contours in Esri file Geodatabase
3-inch color orthoimagery tiles in GeoTIFF and MrSID format
City-wide orthomosaics in GeoTIFF and MrSID format
FGDC-compliant metadata
Survey, control, and vertical accuracy reports
The City again selected Ayres for work in the fall of 2022 using the stereo pairs
from the digital aerial imagery to derive detailed planimetric mapping of the
edge of asphalt for all streets within City of Loveland’s growth management area,
approximately 66 square miles. The planimetric mapping features identified from
the imagery are being mapped to 1” = 50’ scale mapping (1.0 feet RMSE using the
National Standard for Spatial Data Accuracy [NSSDA] testing procedures).

Illinois GIS Consortium:
Lidar, Aerial Imagery, and Planimetric Mapping
The Illinois-based GIS Consortium (GISC) represents one of
Ayres’ most complex geospatial programs and exemplifies
our background in performing large-scale mapping in urban
environments. The GISC is a group of more than 30 communities
in the Chicago region that work together to develop GIS
solutions to support a wide range of applications, including
municipal engineering, planning, forestry, and public safety.
Ayres has been providing high-accuracy mapping and surveying
services to member communities since the 1990s. The GISC
continues to work with Ayres year after year; we are completing
the 2023 mapping projects and are currently planning for the
2024 data collections and mapping initiatives.
The mapping performed for the GISC is designed primarily for daily use in
municipal engineering. Annual aerial missions maintain up-to-date base
mapping data, consisting of 3-inch resolution orthoimagery, 1” = 50’ scale
planimetrics, and 1-foot interval contours derived from high-resolution lidar.
Ancillary products have included leaf-on aerial imagery for urban forestry applications, 3-D modeling of structures, and tall
building-lean mitigation in business districts.
Most of the GISC falls within a 10-nautical-mile radius of Chicago’s O’Hare International Airport. This is one of the most
difficult airspace environments in the United States and presents unique challenges during each flying season. Ayres has
built strong relationships with the Federal Aviation Administration, Terminal Radar Approach Control Facilities, and the
O’Hare Air Traffic Control Tower. Recurring temporary flight restrictions add another dimension to security restrictions in
the area.

MDT Bridge Scour Study, Multiple Locations in Montana
This Montana Department of Transportation (MDT)
project was a bridge scour study of 13 different bridge
sites located throughout the state. KLJ worked
with Ayres as a subconsultant providing surveying
and hydrologic analysis support. A hydrological study
of each site included surveying the bridge structure
and river channel both directions for two-thirds of
a mile. Two of the sites along the Yellowstone River
required aerial lidar surveys for the upland areas.
The first site was located in Livingston and the
second near Custer. These locations did not have
publicly available lidar to analyze the upland areas. KLJ laid ground control
points and ground proofing points for each of these locations. For every site
KLJ established MDT approved control points using static bases lines and
network adjustments.
Perma Curves (MT-200) STTP-F 6-1(36)83,
Paradise, MT
This MDT project is the design of a five-mile stretch of Highway 200 along
the Flathead River east of Paradise. The highway traverses a dangerous
corridor between rock cliff faces and the Flathead River. A portion of the
project lies on the Flathead Indian Reservation and includes culturally
sensitive areas to CSKT. The project corridor was flown with a helicopter
enabled with a lidar sensor. Ground control panels were placed along the
corridor. The crews coordinated access to private land to place that targets
and operated GPS base stations during the flight. Cross-sections of the
corridor were used to ground truthing the flights.
Aeronautical Survey and Airport Airspace Analysis,
Laurel, MT
This Aeronautical Survey with Vertical Guidance for an Airport Layout Plan
developed Instrument Procedure Development for the airport serving Laurel,
Montana. Ground survey included establishing control points using GPS
baselines, tie in photogrammetry control features, identify/measure vertical
obstructions, and topographical survey of the runway and air traffic control
apparatus. Using NGS established GPS control points and KLJ established
aerial targets, photogrammetry and lidar was used to yield two-foot contour
intervals. All the survey data was then transferred to AGIS as part of the final
project report.

City of Bozeman Experience (KLJ)
NEURD Roadway Design and Construction Projects, Bozeman, MT – KLJ provided design
and construction of more than 5,000 linear feet of street and utility reconstruction projects
through the City of Bozeman’s Northeast Urban Renewal District (NEURD). The projects consist of complete removal and
replacement of all public sanitary sewer and storm drain systems within the project corridor, removal and replacement
of public water systems, and full-depth reconstruction of new urban street sections. Street reconstruction consisted of
dedicated vehicular travel lanes with on-street parking, as well as shared-use travel lanes and dedicated bike lanes, traffic
calming elements consisting of intersection bulb-outs, traffic circle, and a section of center-raised median. Construction
also consisted of numerous drive approaches and pedestrian and Americans with Disabilities Act (ADA) facility
improvements. KLJ led multiple neighborhood meetings to communicate construction requirements and schedules and
coordinate resident concerns and business requirements. Permitting acquisition for these projects was required to secure
six separate permits from four separate regulatory agencies. We also provided construction administration services and
assisted with RPR services.
North Wallace Avenue – The North Wallace Avenue project required a significant amount of coordination to minimize
impacts to mature street trees and existing utilities. Design included 5,000 linear feet of new roadway pavement;
new curbs and gutters; ADA facilities; an upsized 18-, 24-, and 30-inch storm drain trunk main and curb inlets; a storm
retention pond; new stormwater pre-treatment structure; replacement of existing water and sanitary sewer systems,
including upsizing Front Street interceptor sewer to a 24-inch main with 36-inch jack and bored cased crossing of
Bozeman Creek; and a new concrete wingwall for the East Tamarack Street Bridge over Bozeman Creek. Extensive utility
relocations were required with many undocumented and abandoned utilities dating back to the turn of the century.
East Tamarack Street Reconstruction – KLJ provided roadway and sanitary sewer main improvements for a 0.20-
mile urban roadway reconstruction project. KLJ was hired to design the reconstruction of one of the oldest streets in
Bozeman. Included in the design are 0.20 miles of roadway reconstruction, upsizing the existing sanitary sewer main to

Ayres is a nationwide professional consulting firm
providing services in photogrammetry, lidar, and digital
mapping; GIS; survey; civil, structural, transportation,
river, and water resources engineering; environmental
science; planning; architecture; landscape architecture;
and mechanical, electrical, and plumbing engineering.
Our employee-owned firm was founded in 1959 by Owen
Ayres, an engineer who instituted many of the practices
we follow: working with clients as a partner; offering
smart, creative solutions; conducting business with the
utmost integrity; and providing employees challenges
and the opportunity to advance and invest in their
company. Incorporated in Eau Claire, Wisconsin, Ayres
now employs over 350 people. Ayres has 11 offices in
Wisconsin, Colorado, Wyoming, Florida, Minnesota, and
California.
Ayres’ geospatial division is based in Madison, Wisconsin.
The geospatial division originated as Alster & Associates
Photogrammetric Engineering (founded in 1951), who
merged with Ayres in 1978. The geospatial division has
over 60 people. Credentials held by these employees
include multiple Certified Photogrammetrists, GISPs,
Certified Mapping Scientists in several specialties, and
Professional Land Surveyors. There are also many highly
trained technicians and project managers, all of whom
have formal education in the discipline of geography. As
shown in the Related Experience section, Ayres’ staff has
brought unparalleled experience providing geospatial
and survey to municipalities throughout the nation. This
breadth of expertise and deep capacity means that Ayres
can simultaneously perform and complete a variety of
projects on schedule and meeting or exceeding client
needs and expectations.
Ayres’ geospatial division provides a diverse range of
mapping services to clients in the West and nationally,
including: • Digital orthoimagery • Planimetric and topographic mapping • Digital terrain modeling (DTM) • Remote sensing • GIS consulting, training, and development
• GPS and conventional survey • Aerial lidar (fixed wing and helicopter) • Oblique aerial imagery • Ground-based lidar (mobile and HD scanning)
Ayres has been providing aerial imagery to local
governments for over 25 years. Ayres helped launch and
develop what is now known as the Wisconsin Regional
Orthoimagery Consortium (WROC). Beginning in 1995
with one regional planning organization covering a
handful of counties, Ayres helped recruit members and
partners, manage funding participation and contracts,
and grow the available products and services until WROC
is now a statewide program that includes state agencies,
county and municipal governments, utilities, and more.
Ayres is the only firm that has ever held the contract
throughout WROC’s history, delivering imagery, lidar, and
related mapping products.
In the past five years Ayres has completed nearly 700
aerial mapping projects. These projects took place in 24
states, including Montana and all its surrounding states.
Ayres’ approach to managing the City of Bozeman’s
project will begin with a dedication to understanding
your needs and designing solutions that address
them. For example, Bozeman is a very attractive area
for relocation, ranking first in the Policom Economic
Strength Rankings for Micropolitan Areas in 2023 for
the fifth consecutive year. Due to the rapid rate of
growth, there will be substantial updates to the building
footprints and changes to the imagery. Ayres has
designated a project manager who is experienced with
municipalities experiencing rapid growth.
Ayres’ proposed project manager, Tyler Kaebisch, will
coordinate the data collection and processing efforts
for the City of Bozeman project. Tyler has experience
managing geospatial projects throughout the country,
with a focus on the western United States. Tyler is
experienced in project management and has a strong

management. Prior to joining Ayres, Tyler servced as a
remote sensing specialist and an inventory and monitoring
GIS specialist for the U.S. Bureau of Reclamation and
the U.S. Forest Service in the Rocky Mountain region. He
has also been involved in numerous projects using aerial
mapping to support mitigation and recovery after natural
disasters.
As project manager, Tyler will update City of Bozeman
personnel during the project to discuss pertinent project
issues as needed. Additionally, he will participate in
weekly internal meetings with Ayres supervisors to
assess the status of the project and address key technical
issues, thereby maintaining high standards for product
specifications and keeping the project on track to meet
the timeframe agreed upon.
One important difference about Ayres compared to some
geospatial firms is that all work is performed in the United
States. Ayres possesses more than enough resources
and uses efficient processes to allow us to accomplish
this project with skilled professionals based in the United
States. There remain only a few geospatial firms that have
their entire production staff within the country; Ayres is
proud to be among them.
Ayres’ subconsultants are KLJ for control survey and
95West for aerial imagery acquisition. Ayres has a
successful history with both firms.
KLJ has four offices in
Montana, including one
in Bozeman, and has
five surveyors who hold
Professional Land Surveyor
licensure with the State of Montana. KLJ’s survey lead,
Justin Stefanik, began his surveying career in Bozeman
and is familiar with the City’s requirements. KLJ has
performed a number of projects for the City and served
as a sub to Ayres on a contract with the Montana
Department of Transportation to perform scour studies on
13 bridges. Under this project, KLJ provided survey control
for aerial lidar data.
95West is a wholly owned
subsidiary of Widseth Smith
Nolting and Associates, Inc., which
is incorporated under the State
of Minnesota. For nearly 60 years 95West (formally KBM
Geospatial) has been providing professional consulting
services in aerial photography, geospatial mapping, civil
and electrical engineering, orthophotography, GIS, lidar,

Ayres Advantages to the City of
Bozeman
Ayres’ is able to offer the City a unique combination of
applicable experience and innovative approaches: 9 Project approach and understanding: Ayres has
been providing lidar and imagery together to local
governments for nearly 20 years. We have proven
ourselves in hundreds of projects, and have brought
new approaches and products such as Elevation
Derived Hydrography (EDH). EDH makes use of lidar
data and asset information, such as culverts and
roads, to provide more accurate understanding of the
expected behavior of water across the landscape 9 Personnel qualifications: Ayres’ key personnel have
been with Ayres for many years – some for decades
– and have personal knowledge of how the process
of the creation of data products has evolved. They
understand the reasons for the data specifications
and how the data will be used. Ayres lead project
personnel and the subconsultants all have significant
Western experience, and the subconsultants have
worked with Ayres in the past. 9 Ability to meet timeline and budget: The City’s
budget aligns with recent Ayres projects that are
comparable in size and complexity, so we are
comfortable that we can perform the work within
budget. In addition, the majority of aerial mapping is
done in the spring every year, so Ayres has over 45
years of experience performing and delivering during
periods of high demand. We make use of cross-
trained personnel who can work on lidar or imagery
as the workflow requires.
9 Location relative to project: Although
headquartered in Wisconsin, Ayres is a national
company, with approximately 60 employees in
the Rocky Mountain region. Ayres is listed as a GIS
contractor on the Montana Association of Geographic
Information Professionals (MAGIP), and Ayres
personnel holds membership in the organization.
Ayres has performed aerial mapping work in
Montana as well as Idaho, Wyoming, Colorado, North
Dakota, and South Dakota. Additionally, KLJ, who is
performing the control survey work, has an office in
Bozeman, and 95 West, who is performing the aerial
data acquisition, will be mobilizing from Grand Forks,
ND, and has experience in the Western United States.
Ayres is currently providing aerial mapping and
processing services for both the City of Bozeman and
the Montana State Library, and has completed work
for the Montana DOT, so we are able to successfully
perform work for Montana clients. 9 Related experience on similar projects: In the past
five years, Ayres has performed 39 aerial mapping
projects that used both lidar and imagery. During that
same period, we have completed 81 aerial mapping
projects for municipal governments, or approximately
one project for a municipality every three weeks,
year-round. We have the capacity and experience to
successfully complete the City’s orthoimagery and
lidar projects. 9 Recent and current work for the City: Ayres is
nearing completion of the City’s Land Use/Land
Cover mapping project, which was contracted in
July, 2023. Ayres also worked with the City in 2018 to
support an EPA brownfield grant application.
J) ADDITIONAL INFORMATION
Additional Options
Ayres understands that the City of Bozeman is asking for cost-effective datasets, which we have responded to on the
preceding pages. Ayres works with many municipalities on similar projects and has found several products that help increase
the return on investment for these projects. We are excited to recommend several options to the City to help increase the
value of your project.
Ayres Lidar Online
Ayres Lidar Online is a 3D, browser-based application used
by a number of local governments to make lidar data publicly
accessible. Users can take measurements between two points
and see the separate horizontal and vertical distances, they
can generate contours and select the contour interval, and
they can view the point cloud to see features such as buildings
and trees.

Optional data creation and hosting of layers can include:• Slope shade bare earth layer • Shaded relief bare earth layer • Hillshade bare earth layer • Elevation surface layer from lidar DEM • Ground lidar point cloud • High vegetation lidar point cloud layer colorized with
imagery • High vegetation lidar point cloud layer colorized with
2021 NAIP imagery • Building lidar point cloud layer (includes bridge
decks) colorized with imagery • 1-foot topographic contour layer • RGB Orthoimagery layer• NIR Orthoimagery layer • Base map streets layer • County boundaries • Municipal boundaries • Tax Parcels
Additional Planimetric Mapping. Ayres can also
extract a wide range of additional features from the aerial
imagery. Below are some common features that can be
extracted in addition to those listed above:• Gravel, dirt, and paved surfaces• Medians• Paths• Parks• Parking lots• Patios• Driveways• Pools• Railroad surfaces• Bridges• Walls• Curb and gutter• Utilities (manholes, vaults, etc.)
Lidar Derived Enhancements. Ayres has derived
a number of other data products from lidar for local
governments. These can be added to the contract as
possible, or provided in the future as the City is able to
utilize them. A few examples of additional products are:• closed depressions where standing water may occur• road profiles for drainage and repair• slope of ditch banks to assess stability and
erodibility• low points in pavement for potential standing water• slope of road banks for safety and stability
assessment
Ayres would welcome the chance to discuss and
demonstrate these additional data products to the City.
For Bozeman’s specific needs, the City needs to be
confident in the ability of the consultant to perform to
the highest quality standards, be responsive to its cost
and timeline needs, and be accountable for the results.
Through previous projects that Ayres completed for a
number of cities, counties, and municipalities, our team
has demonstrated that we are not only reliable, but
that we are also professional in how we manage your
projects. Because our projects start with education
and communication, you can be assured that our team
understands the goals of the City and know that we
appreciate the importance of communication with all
stakeholders throughout the life cycle of our projects.
Ayres has an experienced team of professionals to
address your project goals, including stakeholder
outreach and education, grant writing, project planning,
data processing, and delivery of enhanced products for
specialized uses such as culverts and hydro-modified
DEMs. We have a long history of project success and
are able to handle projects of any size. Ayres handles
thousands of square miles of lidar processing yearly, with
a high degree of expertise.
