Inc. Company Confidential 3 A) EXECUTIVE SUMMARY Aerial Acquisition Geophex Surveys is offering two options for air photo and LiDAR acquisition 1. Simultaneous 3-inch air photo and 12ppm² LiDAR capture with 3-band (R,G,B) aerial imagery 2. Separate 3-inch air photo and 12ppm²LiDAR capture with 4-band (R,G,B,NiR) aerial imagery These acquisition options are offered as 4-band aerial cameras are rarely mounted in the same aircraft as LiDAR sensors. Medium format 3-band (R,G,B) cameras are often used for simultaneous image and LiDAR acquisition, but the large format 4-band cameras are usually mounted in their own aircraft. See the aerial acquisition section in the proposal for more information. Ground Control Geophex Surveys will establish ground control that will provide an accurate control network for both the orthophotography and LiDAR data. These control points will consist of both non-vegetated and vegetated control points for the LiDAR to meet the ASPRS LiDAR accuracy specifications. Aerial Triangulation All imagery will undergo aerial triangulation processing using the ground control and any airborne GPS/IMU data as input information. Orthophoto Processing Geophex Surveys will provide 3-inch, 3-band or 4-band imagery for the City of Bozeman project as defined in the RFP. All imagery will be seamlessly mosaicked, radiometrically adjusted for color, brightness and contrast and processed to the project requirements. LiDAR Processing LiDAR will be calibrated and classified to:  1-processed but unclassified  2-ground  6-buildings  7-low points (noise)  9-water  18-high points (noise) Additional products to be generated include:  DTM  DEM  Hillshade  Raw point cloud  1ft contours  Building footprints  Sidewalk centerlines (within city limits)  Hydro-enforced / hydro-flattened breaklines Quality Control All data is quality checked during processing and prior to delivery. Project Management Geophex Surveys will assign a project manager to the City of Bozeman project. Open and regular communication between the client and the project manager is vital to ensure that all expectations and project requirements including reporting are met and clearly conveyed. Warranty Geophex Surveys stands behind all our data deliverables and we back this commitment with long standing warranties. If the City of Bozeman identifies that the data produced does not meet specifications, Geophex Surveys will fix the substandard data at no charge for a period of 1 year. Our commitment to our clients’ satisfaction is what has kept Geophex Surveys a consistent leader in the mapping industry. Geophex Ltd. Inc.

Inc. Company Confidential 7 Air Photo Acquisition Quality aerial photography begins with a carefully designed flight plan that provides complete coverage and considers terrain variation, location of existing ground control and the configuration of the project area. For the aerial acquisition, Geophex Surveys will partner with Aerial Surveys International which will use either a Phase One medium format or Vexcel Eagle large format camera depending on the option selected by the City of Bozeman. Aerial Photography and LiDAR Acquisition Options The City of Bozeman RFP states that the LiDAR and 3-inch 4-band imagery is to be captured simultaneously in a single flight, however this requirement can be difficult to fulfill due to the nature of how these datasets are typically acquired. Many LiDAR sensors do contain a built-in medium format aerial camera, but these are usually limited to 3-band (R,G,B) imagery only and are generally not used for larger project areas due to the smaller image footprint. If 4-band (R,G,B,NiR) imagery is required, then a large format camera is used, but these are typically not installed in combination with a LiDAR sensor, as the aerial camera and LiDAR sensor will have different flying height and line overlap requirements to meet project specifications, so the project will have to be flown twice regardless. In addition, aerial acquisition firms are often capturing multiple projects at similar times, some of which might only be imagery or LiDAR, and having both an aerial camera and LiDAR sensor in the same plane will severely restrict acquisition efficiency and capability. Option 1 Simultaneous Air Photo and LiDAR Acquisition Option 2 Separate Air Photo Acquisition Flight Lines (yellow) Camera: Phase One medium format Number of Flight Lines:46 Number of Frames: 1,939 Resolution: 3-inch Bands: 3 (RGB) Flight Lines (yellow) Camera: Vexcel UltraCam Eagle large format Number of light lines: 23 Number of frames: 928 Resolution: 3-inch Bands: 4 (RGBNiR) Geophex Ltd. Inc. Company Confidential 8 Ground Control Ground control is fundamental to project accuracy, since accuracy of all subsequent mapping is referenced back to the quality of the original ground control. These control points provide a precise measure of selected positions on the Earth’s surface within the project area. Requirements Geophex Surveys has reviewed the project boundary and orthophoto and LiDAR accuracy specifications and has selected control point locations to meet these requirements, and will be surveyed by a local City of Bozeman firm. All points will be in publicly accessible locations. The control points for this project will serve as control for both the orthophotography and LiDAR to meet the required accuracy specifications. The control for the orthophotography will use photo-id methodology wherever possible. Photo-id ground control uses existing reasonably permanent and easily identifiable ground features as control points and is widely used in the mapping industry. Any additional control provided by the City of Bozeman before the project begins will also be considered. The LiDAR will also use the same control points as the imagery, as well as additional vegetated and non- vegetated control to meet the ASPRS LiDAR control/check point requirements.  Photo-id control: 12 points (will be used for orthophoto and non-vegetated LiDAR control)  Additional non-vegetated LiDAR control: 8 points  Additional vegetated LiDAR control: 5 points  Control point accuracy: ≤±1.5 inches @95% Photo-id Control Layout Geophex Ltd. Inc. Company Confidential 9 Aerial Triangulation Aerial Triangulation (AT) is one of the most critical phases in the photogrammetric mapping process. It defines the geometric network on which all subsequent mapping is based. Geophex Surveys will design the AT plan to maximize the geometric accuracy of all the required products and ensure that we meet or exceed the project specifications. The aerial triangulation process contains five distinct parts:  AT Block preparation  Control Point (CP) measurement  Photogrammetric Point measurement  AT Block Adjustment / Stereo Models  AT Report and Deliverables AT Block Preparation: Contains the most up to date camera calibration report, the captured aerial imagery and the AGPS and IMU data. Control Point Measurement: To support the block adjustment, targeted surveyed ground/photo identifiable control points are measured in stereo softcopy and coded to provide a plate coordinate data file. This file, together with the file containing the ground coordinates of these points becomes part of the input to the AT adjustment software. Photogrammetric Point Measurement: This creates additional ground photogrammetric points at key locations on the aerial photograph to support setting-up of photogrammetric models and minimizes the expense of extra control from survey points in the field. Additional points are measured on shorelines of hydrographic features to ensure that lake surfaces will be level and that watercourses maintain a correct directional flow. The resulting fit of the points for each model is reported as statistics which are used as guides to determine if points need to be re-read in order to improve their accuracy or if more points are required. This is an important part of the internal quality control process carried out during the AT. AT Block Adjustment/Stereo Models: The AT adjustment software is run and incorporates a free-net adjustment, support of GPS and IMU data, and advanced graphical display tools allowing block visualization in 3D. The final product of the AT process includes a set of adjusted coordinates and exterior orientations for the photography. This information is used for data collection (compilation) with softcopy stereoplotters and for orthophoto production. The end results of the adjustment process are stereo models that will achieve the highest accuracy results for the City of Bozeman project. AT Report and Deliverables: Geophex Surveys will deliver a final report upon completion of the AT process which will provide and executive summary of the AT solution and its results, a description of the adjustment process and QC checks for accuracy, a description of the software used to perform the adjustments and a listing of the final adjusted coordinates in a format agreed upon during contract negotiations. Geophex Ltd. Inc. Company Confidential 10 Orthophoto Rectification and DEM Requirements Geophex Surveys will provide 3-inch 3-band or 4-band imagery for the City of Bozeman project as defined in the RFP. All imagery will be seamlessly mosaicked, radiometrically adjusted for color, brightness and contrast and processed to the project requirements. Having successfully processed many city and county projects throughout North America, including in Montana, Geophex Surveys understands the orthophoto accuracy and esthetic requirements expected by the City of Bozeman. Orthophoto Production Process An overview of our orthophoto production process can be summarized in the following steps:  Aerial photography is received from the acquisition contractor and loaded onto the network  The aerial photography is inspected for area coverage and overall quality prior to processing  Aerial Triangulation is performed utilizing the AGPS/IMU data, ground control data and imagery  The bare earth from the new LiDAR will be used as the DEM  Every frame of photo is rectified and quality checked for accuracy and quality  Every rectified frame is color balanced and adjusted for contrast and brightness, and processed in large blocks to maintain project consistency  All imagery is mosaicked using a software generated best path and then inspected and edited if required  Image tiles are clipped out and then thoroughly quality checked for any radiometric, mosaic, or smearing issues and fixed if required  Images are processed into final delivery formats and delivered to the client DEM Geophex Surveys will use the bare earth from the newly captured LiDAR as the DEM for the orthorectification processing. This DEM will provide a continuous and seamless surface to ensure that the imagery is correctly rectified and will accurately reflect the ground features throughout the entire project area. Image Rectification Our orthophoto production process will rectify every frame of the 60% forward overlap photography. Every rectified frame is adjusted for color and contrast to provide project-wide radiometrically balanced imagery. During orthorectification and mosaicking, the imagery is examined for any artifacts resulting from optical and radiometric distortion, including such issues as structure/tree displacement (lean), hot spots, as well as tonal contrast between contiguous features on adjacent frames. The final orthophoto product is comprised of center portions of every rectified frame as required to ensure continuous, seamless imagery across the project area. Radiometric Balancing To ensure quality data, the aerial imagery is manually adjusted for radiometric differences to provide natural color and contrast and correct for any areas which exhibit exposure or color variation. These adjusted images are then processed using software which automatically applies any additional corrections for radiometric non-uniformity and color/contrast blending, to provide large radiometrically uniform blocks of rectified imagery. The result is a set of adjusted input images which exhibit consistent contrast and color across the entire project area. Geophex Ltd. Inc. Company Confidential 11 Bridges and Overpasses When orthorectifying imagery containing bridges, decks and elevated roadways, the DEM will be processed to include these above ground features. This will ensure that the elevated features rectify in their true position and are not subject to “layover” and be incorrectly positioned in the final imagery. Reduced Lean Each ortho mosaic is inspected for features such as tall buildings, towers and trees to ensure that the best image available exhibiting the least amount of lean is used. If necessary, the seamline is adjusted to minimize leaning of tall above ground buildings or structures. Seamline Edits Mosaic seamlines are edited to minimize any visible mosaic lines within the image tiles. Seams are examined and revised if necessary to avoid structures and other problem areas which can cause displacement and aesthetic issues. Editing seamlines ensures that our clients receive the best possible seamless orthophotography. Accuracy checks Our orthophoto imagery is checked against control points, checkpoints, or other forms of control (provided or generated) to ensure that delivered data meets project accuracy specifications. Quality Checks and Corrections At Geophex Surveys, imagery is checked following each processing stage to ensure that the inputs for the next step are correct. This methodology greatly reduces errors that are carried through all the production stages and leads to a more error-free final product. Any errors that are found by our senior technicians are either fixed by them, or returned back to production for repair, before being quality checked again. Our multiple quality assurance steps along with Geophex Surveys’ data warranty, ensures that our clients receive high quality data to their satisfaction. Geophex Ltd. Inc. Company Confidential 12 LiDAR Acquisition and Processing Sensor The LiDAR will be captured using an Optech T2000 aerial LiDAR sensor. The T2000 provides the latest technology for airborne LiDAR solutions, providing more power and accuracy into a small footprint than any other sensor. Designed for everything from wide-area mapping to corridor surveys, the T2000 is a universal sensor that rivals larger systems with its ultra-dense data and industry-leading measurement precision and accuracy. LiDAR Flight Plan The LiDAR flight plan is the same as the aerial photography acquisition flight plan using the medium format Phase One camera, with the addition of crosstie lines to support accurate relative line calibration processing. LiDAR Flight Plan  LiDAR Sensor: Optech T2000  Number of flight lines: 46  Point density: 12ppm² Geophex Ltd. Inc. Company Confidential 13 Precision Airborne GPS and Inertial Measurement Sensors To aid in project accuracy, all LiDAR is captured in conjunction with onboard Airborne GPS (AGPS) and Inertial Measurement Unit (IMU) sensors. AGPS utilizes satellite positioning to provide an accurate, cost effective and rapid method of providing control and ensures accuracy of acquisition data, and IMU uses extremely sensitive motion-sensing technology to record any change in aircraft orientation (roll, pitch, yaw). AGPS data together with IMU data can reconstruct the exact position of the aircraft during LiDAR acquisition and use this information as part of the calibration. LiDAR In-Situ Calibration Before the LiDAR project acquisition, a calibration flight will be flown to ensure that both the horizontal and vertical measurements are within the project specifications. The calibration flight is usually flown over a known area with little air traffic and tree cover, and that contains some open areas, buildings, and a GPS ground reference station. Often several short parallel flight lines are flown in an east/west direction and then overlapped with several lines oriented north/south. This calibration flight will be processed and the results analyzed to determine if there are any calibration or sensor accuracy issues. LiDAR Acquisition Quality Control Aerial Survey International will be monitoring the quality of the LiDAR acquisition during and after the flights. Optech’s Flight Management Software (FMS) generates real-time (RT) las files which are sample of the real time range values that are being returned to the instrument and swath boundaries. These files are inspected during flight to check the performance of the sensor and the integrity of the data collected. Sensor operators are able to check each laser swath for atmospheric quality, and full collection of project boundaries. Optech’s FMS also provides the sensor operator and pilot with flight line orientations and distance, PDOP, and the sensor parameters LiDAR Calibration Following the establishment of the ground control and the LiDAR acquisition, the LiDAR data will undergo calibration to ensure that it meets the positional accuracy as per the RFP specifications. The calibration methodology performed by Aerial Survey International will calibrate the data for relative and absolute positioning in X, Y, and Z planes as described below. Optech Calibration Adjustment After confirmation of complete data collection, the LiDAR adjustment is conducted using a combination of Optech’s LMS, Bayes StripAlign, and LasTools. Interswath height difference maps are created and analyzed to provide a guideline for tie plane generation. Tie planes are matched with control points that are flat and free of obstructions. Water areas are identified and excluded from the adjustment. Areas failing to match are analyzed and the project is exported to Bayes StripAlign. A final adjustment is run in Bayes StripAlign to determine optimal geometry, GPS/IMU drift and shift, sensor polynomial parameters, and correct any matching deficiencies. The final las files are output to be used in downstream processing. Classification The City of Bozeman LiDAR data will be classified to:  1-processed but unclassified  2-ground  6-buildings  7-low points (noise)  9-water  18-high points (noise) LiDAR classification is primarily done using both automated and manual methods. The automated methods include macros, filters and settings designed to isolate specific components from the point cloud. The results from the macros are then manually inspected for areas that appear unnatural or contain errors. Any errors are corrected and the data re-run to ensure that all LiDAR points have been correctly classified. Geophex Ltd. Inc. Company Confidential 14 Initial Classification The raw point cloud LiDAR data is processed into calibrated point cloud strips and tiles corresponding to flight lines. The tiled point cloud is then processed with a series of algorithms to separate the “most-likely” ground returns from other returns. The points will be classified into bare earth and non-bare earth datasets. Noise Removal Noise removal involves the removal or flagging of very high or very low points which fall outside the normal range of typical elevations within the project area. The causes of LiDAR noise vary from atmospheric particulates, to birds or low flying aircraft. Removing data noise is better in the early stages of LiDAR processing so as to exclude them in the minimum and maximum dataset elevations. Automated filtering routines and manual editing remove the points as being valid from the dataset and allow for classification and editing of valid data. Classification Details The angles and distances between points are measured to determine what classification a point should be (ground, non-ground, noise or other). The angle and distance values can be adjusted to be more or less aggressive with the classification of points by varying the incidence angles and estimated distances among neighboring points. The lower points are generally classified as ground returns. Bare earth A systematic visual inspection is performed to fine tune the classification of points among the different categories. To help in improvement for the ground surface, the points that are classified as ground are extracted and turned into viewable TIN and grid surfaces. These surfaces are inspected for areas that appear rough, artificially flattened or truncated, no data areas or have other viewable errors. Following the first edits, a 0.5 m grid of the ground surface is re-exported and hill shade images produced to QC the edited ground surface. For occasional tiles where the QC pass requires considerable “touch- ups”, a second QC pass is performed to validate the classification changes. Once the point cloud data has reached a satisfactory level of classification and accuracy, the final deliverables are produced. Buildings Buildings are classified from the above-ground data that has been separated from the noise. Both semi- automated and manual process will be used to determine that the structures are being classified correctly and which is again verified during the QA/QC stages prior to delivery. Vegetation (Optional) As an optional product, Geophex Surveys can also classify low, medium and high vegetation, as these classifications are often commonly delivered to our clients. See the pricing page for more information. Contours The 1ft contours will be processed from the calibrated and classified LiDAR bare earth DEM. Geophex Ltd. Inc. Company Confidential 15 Vector Line Collection As part of the project requirements, the City of Bozeman is requesting building footprints, public sidewalk centerlines, and breaklines for hydro-enforcement and hydro-flattening. This vector data will all be photogrammetrically collected in 3D stereo from the new aerial imagery.  To ensure that all the required data is captured to the project specifications, experienced photogrammetrist will systematically scan, review, update, and collect new data as required for the project specifications. A 1km x 1km tile grid outline will be generated for each imagery dataset and viewed at a scale that will allow for easy detection of changes and updating (See Fig 1.).  Starting from the bottom left corner, each grid tile will be inspected for features to be collected to the project specifications. After the grid tile has been reviewed, updated and collected, the photogrammetrist will move to the next tile. Following each grid tile update or new collection, each grid tile will be flagged to indicate that the area has been processed. Using grid guide lines ensures that all areas have been inspected and updated and that no areas are missed. Fig 1. Overview of grid lines on the left with arrows illustrating direction of data review, and zoomed in grid tile on right.  Checking Data Seamlessness – Attention will be given to ensuring that data collection is seamless from one tile to the next, and that no unfinished or un-joined features exist where one tile transitions to another. Similarly, data will be checked to ensure that it ties to adjacent map sheets.  Checking Data Completeness – Tile will be checked to ensure that no data features are missed and that all data in the project area have been updated. Data Map Finishing  In this step the shapefiles are edited including data and attribution according to the project specifications.  In-house scripts/routines are executed to check the data.  Topological checks are carried out to ensure data is free of overshoots, undershoots, slivers, data duplication, and that nodes are created at all intersections.  Ensuring the data contains only polylines and polygons.  Feature Code Attributes will be checked utilizing software routines to ensure that all mapped features have the correct feature code attribution.  All feature classes will be checked to ensure correct spatial reference (projection).  Files are prepared for delivery. Geophex Ltd. Inc. Company Confidential 16 Quality Control Geophex Surveys performs rigorous QA/QC checks on all data before it is delivered to the client, and is solely responsible for all deliverables. We verify that the original project plan and specifications have been adhered to, and then follow up with more detailed checking of deliverables. The following section describes in detail the checks that are performed for the aerial photography, aerial triangulation, DEM and orthophoto rectification. AIR PHOTO QUALITY CONTROL Overall Impression Frame contrast and brightness properly balanced and consistent.

Blurred or Smeared Imagery No visible blurring or smeared imagery Shadows and highlights Extremely light or dark areas should be minimized to retain details Format - TIFF, ECW, JPG, Mr Sid, etc Files must be in the format as required in the project specifications Correct Data Verify projection and names for all delivered data. LIDAR QUALITY CONTROL Calibrated LiDAR Quality Control  Relative Accuracy - Following calibration, the LiDAR data will be checked for relative accuracy between swath lines. This check will ensure that there are no accuracy anomalies within the dataset.  Absolute Accuracy - The absolute accuracy will be compared against the surveyed check points that are located on flat open ground to verify that the overall project accuracy specifications have been met. Classified LiDAR and Overall Quality Checks Prior to delivery, the final LiDAR data is checked for any anomalies by using both visual and statistical methods. The point cloud statistics can identify incorrect elevations of the classified data while the visual inspection can identify areas that don’t reflect the true nature of the ground and above-ground features. Additional QC includes:  File Check  Location Check  Gross Void Check  Gross Returns Check  Network/Absolute Accuracy Check  Relative Accuracy Check  Pits, Spikes and Undulations  Overall Density Check  Density by Class Check  Classification Quality Check  Breakline Check  Metadata Check When the data has passed all the quality control checks including verification of the coordinate system and vertical datum, it is clipped to the tiles or boundaries and delivered to the client. Geophex Ltd. Inc. Company Confidential 18 Project Management Geophex Surveys believes that successful projects begin with proactive project management that takes into account our client’s needs, project specifications and available resources and implementation of the steps required to achieve this goal. A well-managed project will eliminate many hours of unproductive effort on both the part of Geophex Surveys as well as our client. At Geophex Surveys, we manage our projects internally through the assignment of a Project Manager who takes responsibility for actively maintaining the project and keeping the production processes moving forward smoothly. Our project manager for the City of Bozeman project will be Kevin Woolf. Kevin is a highly experienced project manager and has successfully managed aerial survey projects of all scope and complexity throughout western US including:  Flathead Montana  Blackfoot Montana  Summit County Colorado  Orem Utah  Santa Maria, CA  Benton Franklin Washington  Washoe County Nevada  Prescott Arizona Many of the projects that Kevin has managed over the past 13 years at Geophex Surveys, and is currently managing, include orthophotography, DEM, LiDAR, and topographic data collection. Kevin will act as the prime contact to the City of Bozeman throughout all phases of project execution, and will also ensure that the project schedule is being maintained. He will keep the Geophex Surveys management team informed of project progress and any perceived problems will be resolved immediately, either internally or in consultation with the City. Our project management style is based on an open relationship with our clients, where all issues are dealt with efficiently and in an atmosphere of trust and co-operation. See Appendix A for Kevin’s resume. Client Communication and Reporting Open and regular communication between the client and the project manager is vital to ensure that all expectations and project requirements are met and clearly conveyed. In consultation with the client, the project manager arranges meetings and a reporting schedule that meets the specific needs of the client. Often at the beginning of a project, the communication is more frequent as the data and image capture takes place and then usually becomes weekly status updates and progress meetings to report project development. Common communication meetings and reporting schedules include: Meetings Meeting Type Period Participants Initiating/Planning meetings As necessary Sales Mgr, Geophex Surveys’ Project Mgr, City’s Project Mgr Project Kick-off meeting Start Sales Mgr, Geophex Surveys’ Project Mgr, City’s Project Mgr Project Progress meetings As necessary Geophex Surveys’ Project Mgr, City’s Project Mgr Project Status meetings Monthly As necessary Geophex Surveys’ Project Mgr, City’s Project Mgr Closeout meetings On Phase/Project close Geophex Surveys’ Project Mgr, City’s Project Mgr Progress and status reports Report Type Period Recipients Responsible Project Plan Start City’s Project Mgr Geophex Surveys’ Project Mgr Periodic Progress Reports Bi-weekly City’s Project Mgr Geophex Surveys’ Project Mgr Geophex Ltd. Inc. Company Confidential 19 Project Implementation Initiation/Administration Project initiation will begin upon agreement on administrative procedures and the issuance by the City of Bozeman of a written notice to proceed. Conference calls will be scheduled to address project start-up issues, determine the prototype/pilot area, distribute necessary source materials, and to address any other technical or procedural issues. Pilot Phase Following successful flight and aerial triangulation, an orthophoto pilot area will be produced and delivered to the City of Bozeman. The pilot area will be delivered in final format and be assessed by the City. If there are no problems, or if the problems are minor and can easily be corrected, the City will provide written notice to proceed to the production phase of the project. The objective of the pilot project is to assure the City of Bozeman that Geophex Surveys can perform the work in a timely manner and according to specified requirements (accuracy, aesthetics, etc.). The pilot area is also used to identify and resolve any unforeseen issues or problems before proceeding to production, and to generate products that define the standard against which the subsequent deliverables will be measured. Production Phase A full project-wide production phase shall commence upon acceptance of the pilot. Geophex Surveys shall propose a delivery schedule for the City of Bozeman’s approval after which, they will provide authorization to proceed for each phase of the project. Each delivery will include all products required. Before shipping deliverables, Geophex Surveys will ensure all deficiencies have been identified and corrected using our quality assurance procedures. Project Wrap-up Upon the final data delivery, there will be a communication between our project manager and the City of Bozeman to ensure that all data has been received. Once the final data has been accepted, there is to be a closing meeting to communicate any project concerns and ensure that all expectations were met, and the final invoice then presented to the client. Warranty Geophex Surveys stands behind all our data deliverables and we back this commitment with long standing warranties. If the City of Bozeman identifies that the data produced does not meet specifications, Geophex Surveys will fix the substandard data at no charge for a period of 1 year. Our commitment to our clients’ satisfaction is what has kept Geophex Surveys a consistent leader in the mapping industry. Geophex Ltd. Inc. Company Confidential 20 Contingency Planning and Risk Management At Geophex Surveys, our project planning and management also includes strategies to eliminate or greatly reduce the effect that unplanned events can have on a project schedule or deliverables. Risk management identifies potential problems before they occur so that contingencies can be planned and executed as needed throughout the life of the project. By doing so, the likelihood of a project finishing successfully is greatly increased. The greatest risks to preventing completion of most aerial survey projects are weather and mechanical difficulties with aerial acquisition. Aircraft Aerial Surveys International is proud of their proven mechanical reliability. With a large fleet of aircraft and a strict adherence to aircraft maintenance schedules, they can be relied upon to ensure that the aerial photography is captured according to the required specifications and schedules. Aerial Camera Depending on the air photo options selected by the City of Bozeman, the aerial photography will be captured with either a Phase One medium format aerial camera, or a large format Vexcel UltraCam Eagle. Both of these camera systems are extremely reliable, and if any unforeseen technical issues arise that cannot be resolved, ASI has additional sensors available that can be brought in as equivalent alternatives. LiDAR Sensor The aerial LiDAR will be acquired using the Optech T2000 LiDAR sensor. As with the aerial cameras, this LiDAR sensor is also very reliable and ASI owns more than one sensor so if any unforeseen technical issues do occur, an equivalent sensor can be brought in as a replacement. Resource Management Resource Management ensures that production resources are available from data acquisition through to delivery. At Geophex Surveys, we have invested in technical infrastructure that allow us to efficiently process complex and large aerial survey projects, and our department managers each have high levels of expertise and many years of production experience. Furthermore, we carefully choose any subcontractors or partners, and only select those that meet our high standards and with whom we can develop and maintain long-term relationships. Data Redundancy To protect the acquisition and production data from any technical issues, Geophex Survey ensures that there are redundant copies kept in off-site locations. In the unlikely event that any large technical problem occurs, we could retrieve the data and continue production with minimal impact to the production schedule. Data Checks At Geophex Surveys, we apply thorough and stringent data checks at all stages of project production. From the flight and control planning stages, through to aerial acquisition, aerial triangulation, and all deliverable data, we ensure that the product being delivered to our clients is of the highest quality. Utilizing the QC tables stated in the previous Quality Assurance section, in addition to further internal QC production checks, we ensure that our clients receive their data to their complete satisfaction.
