Image included on Page 9 or this RFP shows the area to be flown:
All data shall be delivered in both UTM Zone 12 NAD83 (2011) meters, NAVD88 meters and Montana
State Plane NAD83 (2011) meters, NAVD88 meters. 2011 control points for all monuments will be
available from the NGS in February 2012. For more information on the National Adjustment of 2011,
please visit the following website:
http://www.ngs.noaa.gov/web/surveys/NA2011/
Prior to receiving notice to proceed and after negotiations, before any data collection the contractor must
submit a project plan. The project plan will include the following:
1) A map showing the study area boundaries and flight path at a reasonable scale (approx. 1:150,000)
2) Documentation specifying altitude, air speed, scan angle, scan rate, and other flight and equipment
information deemed appropriate.
3) A chart of areas of high Position Dilution of Precision (PDOP), or a list showing the time of the
beginning and end of high PDOP.
4) The proposed ground control plan containing Airborne GPS support. If necessary, the contractor
shall obtain all rights of entry, be responsible for all GPS control information and show all National
Spatial Reference System (NSRS) monuments that will be used for the GPS base stations for airborne
GPS control.
1) Digital Imagery Specifications:
Digital Camera Defined
For the purposes of the Request for Proposal, a digital camera is defined as a stable mechanism that
collects the ground imagery without the use of film in a direct digital format. The City of Bozeman
recognizes that currently the USGS does not provide a calibration report on digital camera
technology; therefore, the vendors must satisfy Bozeman that the proposed camera system has been
21
6
calibrated, modeling all known errors, and exhibits a high degree of internal geometric accuracy,
stability and repeatability.
Orthoimagery shall be acquired only on clear days, leaf-off conditions, with no snow and minimal
puddling of rain water or other weather-related effects obscuring the ground surface. At a minimum,
National Map Accuracy Standards for the production of the Orthoimagery must be adhered to. All
control work shall be completed by the consultant. The camera and magazines shall meet or exceed
the most recent USGS specifications for aerial camera systems. Aerotriangulation/bundle adjustment
shall be performed by the current state-of-the-art analysis software to maximize accuracy of the data.
The consultant shall provide a copy of the AT report.
The proposal shall include a proposed schedule of events necessary to complete the work. The
schedule shall include a process and schedule for the submittal of draft products for City review prior
to final submittals.
Failure to comply with any of these provisions may result in the rejection of the proposal.
a) Photographic Conditions
• Tree Cover. Photography shall be undertaken while the leaves are off the deciduous
trees.
• Clouds. Clouds or cloud shadows must not appear on the imagery. High, thin overcast
is permitted above the flying altitude if it does not cause ground mottling or a discernable
reduction in light levels and/or ground object shadows.
• Well-Defined Images. Collect imagery to obtain well-defined images. Do not attempt
imagery acquisition where the ground is obscured by haze, smoke, smog, dust, or falling
snow, sleet, rain, or other obscuring phenomena. Do not collect imagery when ground is
covered by water (flood), snow, or ice.
• Visibility. The minimum visibility at the time of exposure must be 10 miles or greater.
• Sun Angle. The majority of the project area will be collected when the sun angle is not
less than 40°. In mountainous areas with steep terrain and/or areas with tall trees or areas
with significant urban development with buildings 3 stories or taller (such as downtown
Bozeman), increase the minimum sun-to-horizon angle to acquire the photography during the
times of minimal shadow.
• Tilt will not exceed four degrees for any photographic frame and will average not more
than two degrees for any ten consecutive frames. Relative tilt exceeding six degrees between
any two successive frames may be cause for rejecting that portion of the flight lines.
• Crab angle as measured from the average line of flight will not exceed five degrees. The
course-heading differential between any two successive exposures will not exceed five
degrees.
• Forward overlap will be at least 55 percent between consecutive exposures. The average
sidelap will be at least 20 percent.
b) Image Quality/Radiometry
• There shall be no areas of an orthophoto where the process was incomplete due to image
gaps or lack of data.
• All digital orthophotos shall be radiometrically adjusted as necessary so that adjacent
digital orthophotos can be displayed simultaneously without an obvious visual edge seam
between them. Localized adjustment of the brightness values shall be performed to minimize
tonal differences between the join areas. For this adjustment, the orthophoto judged by visual
inspection to have the better contrast shall be used as the reference orthophoto. Localized
brightness values of the adjacent orthophoto shall be adjusted to that of the reference
orthophoto. When possible and feasible, the area adjusted should be bounded by a tonal break
ground feature such as a road, field line, shadow line, etc. The radiometric adjustment should
not compromise the accuracy, clarity, or resolution of the orthophoto.
• Prior to undertaking full digital orthophoto production, the Contractor shall furnish the
City with sample digital images to evaluate and accept as examples of overall image quality.
The City will select one image, which will become the standard to which all subsequent
digital orthophotos will be compared for acceptance/rejection relative to image quality.

VII. Control
All necessary horizontal and vertical control necessary to provide the deliverables requested in the
proposal shall be completed by the contractor.
Ground control must be adequate to support the accuracy specifications identified below. Some existing
vertical control may be available for the project area. The survey reports & LiDAR data from the 2007
project are available to the consultant. The consultant shall review all horizontal and vertical control for
accuracy and completeness.
Any survey work performed by the consultant shall be done in conformance with Montana survey laws,
regulations and administrative rules.
For survey control work performed by the consultant (or sub-contractors) the following requirements
will pertain:
A brief survey control report in PDF and/or other digital format shall be delivered that contains:
• One digital copy of the control diagram (the survey network scheme).
• One copy of all field notes, horizontal and vertical computations, and control network
adjustments, with the connections to the National Spatial Reference System shall be
clearly shown.
• A digital copy of the new control points established to control the photogrammetry with
all observations and ties, a point description, digital photograph of the monument and the
control point location context, and coordinate values in geographic coordinates and in
both UTM Zone 12 NAD83 (2011) meters, NAVD88 meters and Montana State Plane
NAD83 (2011) meters, NAVD88 meters.
• Survey party personnel, equipment, software, and procedures used.
VIII. Project Schedule
In their responses to this proposal, Respondents shall propose a detailed schedule of performance for
completion of all components of the production process. General project milestones should be presented;
final project milestones will be established prior to project initiation.
IX. Deliverables
The respondent shall submit a delivery schedule.
The Consultant shall deliver to the City for acceptance the following items:
• True Color Digital Ortho Imagery; 1”=100’ map scale (i.e., 1”=600’ photo scale), 6” pixel, true
color, orthorectified digital imagery in GeoTIFF and entire project as mosaic in MrSID format;
• All data in both UTM Zone 12 NAD83 (2011) meters, NAVD88 meters and Montana State Plane
NAD83 (2011) meters, NAVD88 meters.
• FGDC compliant metadata for the imagery in XML format
All products delivered and developed under this proposal shall become the sole property of the City of
Bozeman with no restrictions on use or dissemination.
a) Digital Imagery
6-inch or 0.1524 meter pixel Ground Sample Distance (GSD) digital orthorectified color
digital imagery shall be obtained for the entire project area. Imagery shall be collected with a
minimum 30% side lap and 60% over lap to ensure coverage sufficient to produce stereo
images.
The City of Bozeman wishes to utilize a true aerial digital camera to reduce the amount of
time and expense required for processing, developing and scanning of film that is normally
associated with traditional aerial cameras. Digitally collected imagery ensures the highest
quality imagery from the time of image acquisition because there are no external sources for
contamination or degradation of image quality.

X. Quality Control and Acceptance Procedures
Quality Control
The City retains the sole right to determine contract adherence to quality control requirements. Judgment
that the Contractor is in breach of the quality control requirements may require suspension of any phase
of the contract until such time as the City can determine that such problem(s) have been remedied.
Respondents shall indicate in their proposal a description of the internal quality control processes they
will utilize throughout the various phases of the project to assure that the contract deliverables will be
acceptable. The Respondent may provide forms, flow charts, or other materials to document the quality
control process.
Acceptance Checks
An attempt will be made to complete checks of all deliverable products within 30 days of delivery.
Check plots and ArcGIS data will be subjected to a series of inspections that may include the following:
• Mounting, manipulation, and display of digital files on the City’s GIS system
• Comparison of data and file content with digital orthophotos
• Checks to verify the informational content of the data for completeness, correctness, and
database integrity
• Field checks to ensure compliance with ASPRS accuracy standards
• Other checks against specifications as may be appropriate
The City will be conducting checks of the hard copy and digital data provided.
Acceptance Procedures
After initial checking, work increments will be categorized by the City as follows:
• ACCEPTED: Products that meet specifications and contain no errors, or so few errors as to be
acceptable, will be formally indicated as accepted. The City may assume responsibility for
minor corrections, after which the Contractor will be notified, so that the problems will not recur
on subsequent products.
• RECEIVED-EDITED: The product has a number of errors that do not permit acceptance. For
the product to be accepted, the Contractor must correct all errors noted by the City. The City
will verify through a recorded edit that the Contractor has made all corrections called in for the
first edit.
• REJECTED: The number and character of errors detected by the City are such that the product
is formally returned to the Contractor without a complete edit. The City will formally notify the
Contractor of the rejected status of the product. The Contractor must edit and correct the
mapping for resubmittal to the City. If the City determines that there is an excessive number of
rejected products, the City may require the Contractor to suspend production until the problems
are resolved.
Completion of any required corrective actions shall not affect the Contractor’s production schedule.
Payment for work will not be authorized until the City has accepted the products. The acceptance
procedure will apply to all deliverable products to be received.
