contract language, if any, with their proposal, included as a separate document. If
changes are not requested at the time of proposal submission, the County shall consider that terms and conditions are accepted by proposer. Requests for Contract alterations, modifications, additions, or deletions will not be entertained following proposal submission. Submittal of contract change requests is for

INSTRUCTIONS TO PROPOSERS FOR PITKIN COUNTY CONTRACTS
1. a. A "Proposal" is a responsive, conforming, unconditional, complete, legible and properly executed offer on the Pitkin County Proposal Form to do the work called for
in the Request for Proposals (“RFP”). b. Proposals must be submitted electronically in PDF format and submitted at the time
and place designated in the RFP. Electronic submissions must be clearly marked as a "sealed proposal" with the Service name and the name, contact person, mailing address and telephone number of the Proposer. The County reserves the right to request verification of any original or electronic signature at any time before issuing a Notice of Award. c. It shall be the responsibility of the Proposer to ensure that the Proposal is in proper form and in the County's possession by or before the scheduled time and date of public
Proposal opening. Proposals will not be accepted after the scheduled time and date of opening. Any Proposals received late will be returned to the Proposer unopened, if possible. In the event that it is impossible to determine who the late Proposer is unless
the envelope is opened, the envelope will be opened, the address determined, and the envelope and Proposal returned immediately to the Proposer.
d. If specified in the Request for Proposals, parties who request packages of proposal documents will be required to pay a fee for the document package. All parties who request packages must provide the name of the potential Proposer, along with the
name of a contact person, address, telephone number, and email address for the purpose of dissemination of Addenda or additional proposal information.
e. If a mistake is made or discovered at or after the public opening, the County reserves the right to determine which party made the mistake and whether the mistake is material and, after these determinations, the County, in its sole discretion, shall make the decision whether to accept or reject the Proposal. No advantage shall be taken by either party of manifest clerical errors or omissions in the Proposal documents or the Request for Proposals (and plans and specifications). All Proposers are required to notify the County immediately of any errors of omissions that may be encountered. (See 2.a. and 2.c., below).
f. The signer of the Proposal must initial any alteration or erasure. If provided on the required Proposal Form, the proposal price of each item must be stated in numerals
and words; in case of a conflict, the words will control. In case of conflict between the indicated sum of any addition of figures and the correct sum, the correct sum will control.
g. No reimbursement will be made by the County for any costs incurred in the preparation of a statement of qualifications, Proposals, or attendance at a site
inspection, pre-bid conference or interviews. h. No person, firm, corporation or other entity shall be allowed to make, file or be
interested in more than one Proposal for the same work, unless alternate proposals are called for. A person, firm, corporation or other entity who has submitted a sub-proposal to Proposer, or who has quoted prices on materials to a Proposer, is not
RFP 030.25 Rev. 2021.10.11 CDD Budget Line Item #: 15022100.574000
15
hereby disqualified from submitting a sub-proposal or quoting prices to other Proposers.
2. a. If any person contemplating submitting a Proposal is in doubt as to the true meaning of any part of the Drawings, Specifications or other Proposal or Contract Documents,
or finds discrepancies, errors, ambiguities, inconsistencies, incompleteness or omissions in the Drawings or Specifications or the proposal process, he/she must submit to the Procurement Officer a written request for an amplification, clarification,
explanation, interpretation or correction thereof. Failure to do so shall constitute: (1) acceptance by the Proposer of the Drawings, Specifications or other Proposal or Contract Documents as is, and (2) a waiver by the Proposer of any and all claims arising, or that might arise, out of such discrepancies, errors, ambiguities, inconsistencies, incompleteness or omissions. b. Proposers may propose substitute materials or techniques if such substitution is equal to or better than the materials or techniques described in the RFP and if the substitution
has been submitted in writing at least ten (10) days prior to the public Proposal opening. The burden of proof of equality or superior quality is on the Proposer. If accepted as equal by the County in its discretion, the substitute will be designated as
an alternative on a formal addendum available to all Proposers three (3) days prior to the deadline for Proposal submission, when possible. If approval of any substitute materials and/or processes has not been provided by County prior to the deadline for
proposal submission, proposers may elect to submit an alternate bid with separate pricing and rationalization for the alternate materials and/or approach. County, at its sole discretion, will determine if the alternate meets the needs of the respective project.
c. Any amplification, clarification, explanation, interpretation or correction of the documents will be made only by written Addendum duly issued and a copy of the
Addendum will be mailed or delivered to each person receiving a set of the Proposal Documents. Delivery, as used in these Instructions, shall include electronic delivery through e-mail, facsimile, web-posting or other electronic means. Neither the County nor the Procurement Officer will be responsible for any information, representations, explanations or interpretations of the Contract Documents not in written addenda. d.

delivered to all parties receiving a set of Proposal documents. e. On request, the County will provide each Proposer access to the site to conduct, at
Proposer's sole cost, such inspections, tests and investigations as each Proposer deems necessary for submission of a Proposal. No information provided by County representatives at such a site inspection shall be deemed a waiver of the requirements
of 2.a. and 2.c., above. f. Any Addenda issued during the time of the Proposal process, or forming a part of the
Proposal Documents, shall be covered in the Proposal, and shall be considered a part of the RFP. Receipt of each Addendum shall be acknowledged in the Proposal.
g. If specified in the RFP, a request for qualifications may precede the RFP process.

specified, payable without condition to the County as a guarantee that the Proposer, if awarded the Contract, will promptly execute the Agreement in accordance with the Proposal, and will furnish, if required by the Proposal, good and sufficient bonds for
the faithful performance of the Contract and for the payment to all persons supplying labor and material for the work (see 10.a., below). The Proposal guaranties of all parties except the three highest scoring Proposals will be returned promptly after the opening
of Proposals. After execution of the Contract and issuance of a Notice to Proceed, the remaining two Proposers’ guaranties will be returned. b.

Pitkin County reserves the right to pre-qualify Proposers based on said qualification statements.
c. Proposer also must submit with the Proposal a list of subcontractors, independent contractors and suppliers to be employed under the Contract. If the County has a reasonable objection to any such subcontractor, independent contractor or supplier, it
shall notify the Proposer and the Proposer may then: (a) withdraw the Proposal; or (b) substitute an acceptable contractor or supplier. If required by the Contract Documents, subcontractors, independent contractors and/or suppliers may be required to submit a
Contractor's Qualification Statement. d. Proposals by corporations must be executed in the corporate name by the president or
a vice-president (or other corporate officer accompanied by evidence of authority to sign) and the corporate seal must be affixed and attested by the secretary or an assistant secretary. The corporate address and state of incorporation shall be shown below the

03-revenue-and-finance or upon request for a nominal charge). As such, the Proposer agrees to comply with all applicable requirements of said Procurement Code relating to proposing, contract drafting, contract administration, and ethics. The requirements
of the Procurement Code are incorporated herein by this reference. b. The Proposer shall immediately notify the County Manager in writing of any violation of said Code by the County's employees or agents, which violation is known or should have been known by Proposer, and failure to so notify the County of violations within five (5) days of knowledge of such violations shall disqualify the Proposer from award
RFP 030.25 Rev. 2021.10.11 CDD Budget Line Item #: 15022100.574000
17
of the Contract being proposed and shall be deemed as a waiver of any action or defense that the Proposer may have against the County by reason of such violation of
the Procurement Code. c. The submission of a Proposal shall be conclusive evidence and legal admission that
the Proposer: (1) has no questions, complaints or objections in connection with the Proposal process and/or documents, subject to any requests made by Proposer for amplification, clarification, explanation, interpretation or correction pursuant to
Paragraph 2.a. and 2.c., above; (2) has no questions, complaints or objections as to the completeness, sufficiency, scope or detail of the Proposal Documents; and (3) has full knowledge of the scope, nature, quality and quantity of work to be performed, the detailed requirements of the Proposal Documents including any and all contract documents, the plans and specifications, the site and conditions under which the work is to be performed, the Pitkin County Procurement Code and applicable Colorado law. 5. a. All Proposals will be opened and read in public by name of Proposer only. No
Proposals may be withdrawn after the beginning of the public opening. The County, in its sole discretion, may delay a Proposal opening for no longer than two (2) business days if weather or other circumstances beyond control of Proposers results in delay in
receipt of Proposals. Proposals may be withdrawn at any time prior to the beginning of the public opening or modified by a document executed and delivered in a form substantially similar to the Proposal Form prior to opening.
b. All Proposals submitted must be valid for a minimum period of sixty (60) days after the date of the Proposal opening. During this time, Proposers are investigated, and
Proposals are evaluated. 6. a. Proposals will be awarded to the highest scoring Proposer complying with the terms,
conditions, guidelines, selection criteria, plans and specifications presented in the Request For Proposals. All rights are reserved by the County to determine, in the County's sole reasonable discretion, whether the Proposal meets the needs or a purpose intended and is within the budget. b. Although price may be a major consideration in the selection of a Proposal, the County does not award on price alone. The County may also consider the quality of product as judged by the County; past experience with Proposers, subcontractors, independent
contractors, products or suppliers; qualifications of the Proposers and/or subcontractors, independent contractors or suppliers; services offered; warranties; maintenance considerations; long-range costs; delivery; and similar considerations,
all as specified in detail in the RFP. c. The County reserves the absolute right to conduct such investigations as it deems
necessary to assist in the evaluation of any Proposal and to establish the experience, responsibility, reliability, references, reputation, business ethics, history, qualifications and financial ability of the Proposers and proposed subcontractors,
independent contractors and suppliers. The purpose of such investigation is to satisfy the County that the Proposer has the experience, resources and commercial reputation necessary to perform the work and support any warranties in accordance with the
Contract Documents in the prescribed manner and time.
RFP 030.25 Rev. 2021.10.11 CDD Budget Line Item #: 15022100.574000

d. The County, at its sole discretion, may require the apparent successful Proposer to demonstrate, at a place and time designated by the County, that the Proposal meets
the performance criteria specified, or to otherwise provide documented proof from independent reliable sources acceptable to the County that said performance criteria will be met prior to final acceptance of the Proposal. The burden of proof of such a
demonstration is on the Proposer. In the event that the apparent successful Proposer fails to demonstrate or provide acceptable proof of meeting required performance criteria, that proposal will be rejected and the next eligible Proposer in the selection
ranking will be invited to participate in the same process until a proposal meeting performance criteria is found within the ranking of eligible Proposers. The County reserves the rights to reject any or all Proposals or to otherwise accept the Proposal which in the County's sole discretion is in the best interest of the County. e. Pitkin County reserves the right, if it deems such action to be in the best interests of the County, to reject any and all Proposals or to waive any irregularities or informalities therein. Any incomplete, conclusory, false or misleading information
provided by Proposer shall be grounds for rejection of the proposal. If proposals are rejected, the County further reserves the right to investigate and accept the next best proposal in order of ranking or to reject all proposals and re-solicit for additional pro-
posals. f. Any questions or disputes involving the documents or procedures not covered by these
Instructions or other Proposal Documents shall be resolved by the Procurement Officer on the basis of fairness, custom in the industry, maximization of competition and best interests and convenience of the County.
7. Issuance of Notice of Award, execution of Contract Documents and issuance of a Notice to Proceed shall be as specified in the Contract Documents and in accordance with the Pitkin
County Procurement Code. County standard practice is to first notice the top-ranked proposer and enter into a final contract agreement prior to notifying unsuccessful bidders. Non-awarded bidders will be notified of the County’s decision and shall be offered an optional debrief conversation of the bidding and evaluation process; debrief conversations may be offered prior to contract signing but, in most cases, will not be scheduled until a contract has been finalized. 8. Contracts will be executed on standard Pitkin County Contract documents and/or by separate
agreement with the Proposer. Copies of any applicable standard forms are included with the Proposal Documents. The County reserves the right to negotiate with the Proposer for contract terms not specified in the Proposing Documents. Any changes from the Pitkin
County standard form contract may result in a delay in the issuance of a Notice to Proceed in order to obtain any necessary County Attorney review of changes from the standard form. Proposer agrees that any such delays shall not be grounds for either additional compensation
or an extension of time to complete the work that is the subject of the Proposal. 9. If any contract awarded as a result of a Proposal extends beyond the calendar year, nothing
herein shall be construed as an obligation by the County beyond any amounts that may be, from time to time, appropriated by the County on an annual basis. It is understood that payment under any Contract is conditional upon annual or supplemental statutory
appropriation of funds by said governing body and that before providing services, the Proposer, if he/she so requests, will be advised as to the status of funds appropriated for
RFP 030.25 Rev. 2021.10.11 CDD Budget Line Item #: 15022100.574000

services or materials and shall not be obligated to provide services or materials for which funds have not been appropriated.

Company Background
Technical Application & Consulting, LLC (TAC) was established in 2011 in Topeka, KS and continues to be
one of the only Service-Disabled Veteran-Owned Small Business (SDVOSB) in the airborne remote sensing
industry. We provide large and small scale photogrammetric/LiDAR mapping, hyperspectral imaging, and Full
Motion Video to both the government and private sector. Since inception, TAC continues to expand, acquiring
more aircraft, facilities, personnel, and equipment to tackle larger projects of varying complexity.
Our diverse team is largely comprised of military veterans and industry professionals with expertise and real-
world experience in geospatial intelligence (GEOINT), large and small scale photogrammetric/ LiDAR
mapping, geospatial postprocessing, and CONUS/ OCONUS special mission aviation. TAC understands the
requirements set forth by many agencies and strives to exceed them repeatedly. To date, we have mapped over
250,000 square miles, from Alaska to Chile and everywhere in between.
TAC has found remarkable success in bridging the gap between the client and the actual work performed. It has
become all too common for large engineering firms without aircraft to
win airborne mapping contracts and subcontract the aerial work. This drastically increases the price of a project
and ensures it will not adhere to the timeline. By eliminating the third party, TAC can pass the time and money
savings back to the client while assuring total control over project timelines.
With in-house postprocessing, TAC can create
quality deliverables faster than firms who
“offshore,” or send the data overseas for
postprocessing. Our central base of operations at
Philip Billard Municipal Airport (KTOP) allows
our air crews to mobilize rapidly and reach
much of the country in 4 hours. TAC utilizes a
horizontal organizational structure which
negates corporate bureaucracy and enables our
staff to make decisions which best suit the
client’s needs. This strategy has put TAC in a
category of its own and allows for efficient, safe
flight operations as well as more streamlined
postprocessing workflows. TAC is the low-risk,
resilient solution for Pitkin County.

Project: Aerial Stereo Imagery for Monitoring Extractive
Sites in Colorado
Client: Bureau of Land Management- Royal Gorge Field Office
Point of Contact: Amber Pike
Phone Number: 719.269.8750
Location: Rocky Mountains, South-Central Colorado
Period of Performance: 2024
Services: Aerial Acquisition, Digital Orthophotography, Photogrammetric production
TAC was awarded Sol_140L1724Q0064 to assist the Bureau of Land Management (BLM) in monitoring
extractive mining sites within the Royal Gorge Field Office (RGFO) jurisdiction. The project area consisted of
14 extractive mine sites scattered around 6 counties in Southern Colorado. The mine sites were all planned to
ensure full stereo coverage at 60% overlap and all lines were collected in opposing directions.
TAC collected the high resolution, 3-inch RGB imagery over the span of four days in late October 2024 with a
Cessna Turbo 206 equipped with an UltraCam Eagle large format digital mapping camera. TAC delivered an
Exterior Orientation (EO) file providing aircraft location and attitude information for each photo event in the
project area along with high resolution imagery to support the 30-centimeter RMSE accuracy requirement desired
from the BLM.
BLM-RGFO intends to use stereo-imagery to calculate the
volume of earth/minerals extracted from each mine over the
course of the year. The imagery will be compared to previous
years’ data for change detection and analysis.

In support of the Western Wildfire Campaign, TAC was
contracted to capture pre- and post-burn, fixed wing aerial
LiDAR and digital orthoimagery for the Monroe Mountain area
in Utah and sites in the Kaibab National Forest in Arizona.
TAC collected 16 ppm LiDAR and 7 cm orthoimagery covering
approximately 300 square miles of Monroe Mountain in UT in
the fall before the controlled fire season. After the controlled
fires were completed, TAC then collected LiDAR and imagery
of the two burn areas that covered approximately 7 square
miles. TAC then worked on production of derivative mapping
products including tiled classified LiDAR (ASPRS standards,
LAS 1.4, ICSM Level 1 and Level 2); tiled unclassified LiDAR;
contour geodatabase (0.5m resolution); DTM geodatabase
(0.3m resolution), pit-free canopy height geodatabase (0.3m
resolution), flight trajectory shapefile, tile index shapefile, and
metadata.
For the most recent iteration of FASMEE, TAC mobilized a
Cessna T206 with Optech Galaxy T500 LiDAR system and
Cessna 310R with a PhaseOne PAS280 to collect the imagery.
TAC’s air crews routinely contended with rapidly changing
weather conditions, turbulence, paragliders, and 70 knot+ winds
aloft.

Project Management Approach
Quality ultimately begins with leadership, where the strategy and success of our business is dependent upon
client satisfaction. TAC owner and operations manager, Tracy Blocker, has decades of real-world experience
managing DoD and Commercial remote sensing projects worldwide in a variety of challenging environments.
From the dense rainforests of Central Africa to the mountains of Central Asia and South America, and
everywhere in between.
Mr. Blocker developed a Quality Management System which fully complies with, and is based on, the
underlying principles of ISO 9002-2008 quality standards and in its continued commitment to quality service.
TAC’s QMS includes a quality policy, objectives, a quality manual, documented procedures, and records. The
quality manual outlines the quality system implemented by management, and it is adhered to by all members of
TAC. The quality manual includes the standard operating procedures and processes by which a sequence of
operations is performed to ensure client requirements are met and is fully compliant with ISO 9001-2008
requirements and principles.
In 2019, TAC’s overall program management was strengthened during the completion of a yearlong Mentor-
Protégé Agreement (MPA) with Fortune 500 company, L3Harris, under the DoD Mentor-Protégé Program
RFP 030-25 2025 AERIAL PHOTOGRAPHY SERVICES | Technical Applications & Consulting
(MPP). While the main purpose of the MPA served to enhance the abilities of the warfighter, L3Harris Program
Managers came to TAC’s facilities to instruct and bolster our business development and project management.
Proposed Project Schedule
Tentative dates will be based on the actual collection window. TAC’s project manager will work directly with
Pitkin County to develop a schedule which best serves your timeline. Once notice to proceed has been given,
TAC will mobilize an aircrew to begin collection when weather conditions are favorable. Postprocessing will
begin immediately following the acquisition flights.

Work Plan & Aerial Acquisition
Kickoff Meeting: Prior to the project first steps,
TAC’s Project Manager, Tracy Blocker, will conduct a
teleconference with Pitkin County’s key personnel to
review the project scope as well as establish a pilot area if
needed. We will also address the number of ground
control points (as seen at the bottom of this document)
and answer any additional questions the County might
have.
Flight Planning: The data collection phase begins with
careful mission planning to determine flight paths, camera settings, and environmental factors. Once Pitkin
County issues a notice to proceed, an available air crew either from our facility in Topeka, Kansas or their
current location, will be dispatched to Pitkin County. As weather is often the greatest setback to aerial collection
and safety, our experienced aircrews will choose a favorable window to facilitate the collection. This will
ensure inclement weather does not gain the upper hand and the project is completed expeditiously.
Collection Flights: TAC will obtain any licenses and authorizations for overflights of the project area.
TAC’s Chief Pilot will notify airspace controllers as soon as possible and provide them with a flight line layout
to assist in coordination. We do not expect any issues as we are familiar with the airspace and environmental
constraints in the project area from the completion of Aerial Stereo Imagery for Monitoring Extractive Sites in
Colorado, FASMEE, and others.

images: 3179
Number of Flight Lines: 72
With the total number of lines
and images doubled from the
6” plan, a substantially longer
acquisition period can be
expected.
Flying half the altitude of the
6” plan introduces multiple
terrain-related issues into the
equation.
The region of the AOI
encompassing the north/
northwest slopes of Mt.
Sopris presents a significant
safety of flight risk as
denoted by the red and white
hash marks in the graphic
below from our flight
planning software.
Additionally, the areas in
indicated in pink
(predominately valleys) will
not be subject to 3” GSD
imagery on account of drastic
differences in elevation, thus
not meeting the criteria
outlined in the RFP.
TAC modeled this using all
available lens for our large
format cameras and kept
getting the same results.
Areas in Pink will not meet 3" GSD
requirements. Red and White
hashmarked area poses extreme risk to
aircrew.

Product 4: Custom solution to 3” GSD issues.
Given the County’s potential interest in splitting the project into different extents and the states issues
mentioned above, TAC devised Product 4 to achieve a maximum 3” GSD coverage of population centers.
Product 4 allows for the seamless mosaicking of Aspen, Snowmass Village, and Basalt without many of the
terrain-related GSD issues. This option supports more detailed change detection, planimetric, cadastral, and real
property analysis.

TAC believes Pitkin County would benefit the most from a combination of Product 1 and Product 4 in
order to maximize usage of ground control.
Collection QA/QC: The aircrew will make an exploratory pass over the county to ensure there are no
prohibitive conditions on the ground (flooding, snow, standing water, etc.). To achieve Pitkin County’s stated
goal of imagery covering the full extents of the flyover area, TAC will conduct the acquisition flights at
preplanned altitudes using the Vexcel UltraCam Eagle. This ensures 40% sidelap and 60% endlap. The
integrated flight management system aboard each of our aerial collection platforms allows the crew to QC
imagery in real time, allowing for costly mistakes to be avoided and the survey to be completed in the least
number of flights possible.
Imagery QA/QC: All of TAC’s remote sensing systems are mounted in
Somag-AG gyro-stabilized mounts (GSM), which track the planned flight
line ground track. These mounts virtually eliminate in-flight issues such as
crab, roll, pitch, and turbulence commonly encountered in non-GSM
systems. This allows our air crews to fly in weather conditions that would
normally prohibit collection without sacrificing data quality and integrity.
In addition to reducing environmental challenges, the GSM-mounted
systems increase productivity by reducing side lap requirements. This
equates to confidence in the collected data and decreased collection times
Sun Angle: All acquisition flights will be conducted with the sun not less than 30 degrees above the horizon
and ground. All of TAC’s flight management systems are equipped with sun angle displays to ensure we
maximize collection windows. Given the elevation and surrounding mountains, the selected air crew will ensure
there are no extensive ground shadows present.
Flight Conditions: TAC will collect RGB and NIR aerial photography during the leaf-free season in the
spring of 2025 when deciduous trees are barren. Imagery will be collected when the ground is free of snow,
haze, smoke, and cloud shadows. Additionally, TAC will ensure all streams and rivers are within their banks
RFP 030-25 2025 AERIAL PHOTOGRAPHY SERVICES | Technical Applications & Consulting
prior to collection. TAC has thousands of collection hours to these exact specifications, and we understand the
challenges involved with numerous environmental factors.
Ground Control: TAC will deploy experienced field crews to set ground
control points within the Pitkin County Project area prior to collection. Crews
will utilize previously established control points where available or new photo
identifiable points. TAC will utilize this control with published coordinates for
the Aerial Triangulation, Ground Control, and CORS (commercial reference
networks) for Airborne GPS acquisition. Field crew(s) are equipped with
Trimble Dual Frequency GNSS R10i receivers and TSC Controllers as well as
our full suite of survey grade instruments. Ground control points will be
observed/occupied with GPS when conditions are suitable.
In all other cases control point pairs will be set with GPS and control point
surveyed using our Trimble R10i. The origin for all ground control points will come from the appropriate
National Geodetic Survey (NGS) Data sheets, referenced horizontally coordinate values to Colorado state plane
NAD 83: 2011, measured in U.S. Survey Feet. CO Professional Land Surveyors will work with field crews to
oversee all aspects of the collection and post-processing of ground control. A final report incorporating all
aspects of ground control, flight mission, and image processing results will be prepared and delivered.
In addition to the ground targets, TAC will supplement with airborne GPS data derived from GNSS and the
highly accurate Inertial Measurement Unit coupled with the sensor to ensure horizontal and vertical accuracy.
TAC intends to subcontract Mr. Jake Carroll, owner of Bearing Tree Land Surveying, LLC, a Colorado-licensed
surveyor with over 20 years of experience, to oversee the survey crews and placement of ground control points.
TAC has utilized Mr. Carroll for setting control points for dozens of projects to date. We have created a
preliminary control layout and included an overview shown in Exhibit A at the end of this document.

Aircraft
TAC owns and operates the largest fleet of aerial mapping aircraft
of any firm in the small business category including: (4) Cessna
Turbo 206 (TU206), Cessna T310R, Pilatus PC-6, Piper Turbo
Aztec, Cessna C208 Grand Caravan, and Bell Jet Ranger helicopters.
All aircraft are equipped with precision navigation and the latest
photogrammetric and LiDAR systems. Our air crews, comprised
largely of veterans, are highly trained and experienced, boasting
thousands of operational flight hours. All of TAC’s aircraft are
equipped with dual-frequency Global Positioning Systems (GPS),
IMUs and real-time heads-up displays (HUDs) for mission
management. The performance of our aircraft is more than adequate
to complete the project in accordance with the technical
specifications.
TAC’s fleet is meticulously maintained beyond Federal Aviation
Administration and Civil Aeronautics standards to ensure
unscheduled maintenance does not disrupt collection flights. All
aircraft maintenance is conducted in our facility in Topeka, Kansas
at Phillip Billard Municipal Airport (KTOP) by FAA-licensed A&P
mechanics under the supervision of A&P Inspection Authorities. In
the unlikely event that the aircraft utilized for the LiDAR &
imagery acquisition encounters maintenance issues, TAC can
quickly replace the aircraft with one of our other mapping
platforms, keeping the project on schedule. All TAC aircraft are
equipped with air to ground communications for continuous
mission control and public safety.
TAC’s four Cessna 206s are operated thousands of hours a year
without a safety incident or maintenance delay, which speaks
volumes for our aircrews and maintenance professionals. TAC
aircraft are all outfitted with modern Garmin avionics, emergency
location transponders, medical kits, and are certified to fly IFR.

Vexcel UltraCam Prime & Eagle
TAC uses the UltraCam Prime and UltraCam Eagle large format, digital
mapping cameras designed for nadir photography. Developed by Vexcel
Imaging, the UltraCam combines high-resolution imagery with advanced
georeferencing capabilities, making it the ideal tool for capturing accurate,
large-format imagery. The system features multiple sensors, including large-
format CCDs (Charge-Coupled Devices), which enable the capture of
detailed, high-quality color and near-infrared imagery across massive
swaths of the earth. Capable of 300 megapixels, The Eagle has become
TAC’s go to large format digital mapping camera as its capabilities reduce
the amount of flight lines needed up to 40% in some instances depending on
Ground Sample Distance (GSD). TAC has proudly operated UltraCam
systems since 2015 and continues to do so as their impact on multiple
statewide imagery contracts cannot be overstated. A unique benefit of the Eagle is its ability to drastically
reduce flight times, reducing TAC’s carbon footprint. Additionally, the Vexcel Eagle or Prime sensors can be
deployed in all of TAC Cessna 206’s, Cessna Grand Caravan, and Pilatus PC-6.
To meet the requirements of 6” GSD or better outlined by Pitkin
County, TAC plans to use a Cessna 208 Grand Caravan equipped with
the Vexcel UltraCam Eagle. The combination of extended flight times
and the Eagle’s massive footprint on the ground means the acquisition
flights will be completed faster than using other camera systems. In
addition to the Vexcel UltraCam Eagle and Prime large format digital
mapping cameras, TAC owns and operates the following large and
medium format mapping cameras.
• Leica ADS100 Large format push broom
• PhaseOne PAS 150
• PhaseOne PAS 280

Technical Approach to Generation of Orthophotos
GPS-IMU Post Processing: Airborne global positioning system (GPS) and inertial measurement unit
(IMU) data will be acquired during the acquisition mission, providing sensor position and orientation
information for geo-referencing the imagery data. Airborne GPS observations will be collected in 1 second
intervals, and IMU observations collected at a frequency of 500Hz.
The airborne GPS dataset will be differentially corrected using Applanix PosPAC MMS version 9.1 software in
tandem with their PP-RTX service. POSPac PP-RTX is a cloud-based global GNSS correction service which
utilizes Trimbles RTX technology to provide cm level post-processed positioning accuracy without base
stations. The Trimble RTX technology utilizes data from a dedicated global network of tracking stations to
compute corrections to satellite orbit and clock information as well as atmospheric delay models.
PosPAC computes the GPS dataset corrections in both forward and reverse chronological sequence, obtaining
two solutions for the GPS trajectory. Differentially corrected airborne GPS data is then merged with the
airborne IMU dataset in the PosPAC MMS software. PosPAC MMS then applies the reference lever arms for
the GPS and IMU measurement systems during processing to determine the trajectory (position and orientation)
of the acquisition mission. PosPAC MMS will then create a smoothed best estimate of trajectory (SBET) file
includes direct georeferenced events for each exposure.
Aerial Triangulation: TAC uses a variety of AT software, but SimActive Correlator3D (C3D) software has
proven to be the most highly productive and versatile tool. C3D is a patented end-to-end photogrammetry
solution for the generation of high-quality geospatial data from aerial imagery. Using direct geopositioned data
from an Exterior Orientation (EO) file and color-corrected image data are used as inputs to the block bundle
adjustment portion of the aero-triangulation workflow. The data from individual acquisition missions is loaded
into the C3D software for processing. Ideally the entire project area is processed as a single block.
An automated point measurement (APM) algorithm is run to obtain image coordinate and ground coordinate
measurements of tie points within the overlap regions between consecutive exposures along a flight line and the
side-lap regions of neighboring flight lines. These coordinate measurements and the direct geopositioned data
from the EO provide the observations for the least-squares block bundle adjustment algorithm implemented in
C3D.
The block bundle adjustment algorithm solves systematic errors in the exterior orientation data extracted from
the post-processed GNSS/IMU trajectory such as IMU bore-sight angles, and GNSS/IMU solution drift. A
unique set of systematic errors may be determined for each lift, permitting large blocks consisting of multiple
lifts to be solved simultaneously. Bundle adjustment
statistics (standard deviations and residuals) are reviewed
following each bundle adjustment iteration. If resulting
statistics exceed the acceptance criteria, the individual
point residuals are then removed or ignored, and the
solution is then refined. This process is followed by
another iteration of bundle adjustment and statistical
review. The orthorectification process can then be started
after the resulting standard deviations and residuals meet
the predefined acceptance criteria.
RFP 030-25 2025 AERIAL PHOTOGRAPHY SERVICES | Technical Applications & Consulting
Radial Displacement: We manually correct radial displacement and distortion of bridges and
overpasses through a series of pre-rectification measures and post-processing edits. All features will be
checked during periodic and final QA/QC checks prior to completion.
Rectification & Surface Modeling: Our Team has rectified and mosaiced hundreds of thousands of
orthoimage tiles during their photogrammetry careers and routinely delivers RGB and color infrared (4-band)
data formats at Ground Sample Distance (GSD) resolutions ranging from 1 inch to 1 meter. Our experience over
that time includes processing data from almost every commercially available analog and digital imaging sensor,
throughout the varied topography of the United States and OCONUS. The TAC team’s production resources
include over 25 dedicated digital orthoimage workstations.
TAC photogrammetrists use the rectification
module in SimActive’s Correlator3D (C3D)
software for orthorectification of the high-
resolution imagery. The rectification process
takes the block bundle adjustment solution
from the aero-triangulation process and
rectifies the imagery to an existing bare-
earth surface model. TAC typically prefers to
rectify the imagery to LiDAR data collected
at the same time as when the imagery was
acquired. LiDAR ground points are used to
generate a gridded surface model for input
into C3D. If LiDAR is not a viable option,
TAC will produce an auto-correlated surface
model from stereo imagery. The C3D auto-correlation module is used to generate mass points for each image
frame stereo pair. The auto-correlation module uses an automatic point measurement algorithm to find mass
points in the stereo overlap regions within a flight line.
The resulting Digital Surface Model (DSM) will produce mass points of the ground surface and above ground
features. The above ground features are then filtered out to create a Digital Terrain Model (DTM) representing
only ground features for use in the orthorectification process. C3D has built-in geometric algorithms that
identify and filter above ground features from the DSM. The filtered DTM is then interpolated to a regularly
gridded bare-earth model for use in the rectification stage. The DTM is reviewed for any elevation anomalies
that would introduce image smearing during orthorectification, and manual edits made as necessary to remove
any anomalies.
The C3D rectification module is used to generate an 8-bit or 16-bit, color corrected, orthorectified image file for
each frame. The band order of the orthorectified image is output as: Red in Band 1, Green in Band 2, Blue in
Band 3, and Near-Infrared in Band 4. The orthorectified images are validated for relative horizontal accuracy by
visual inspection. Our photogrammetrists manually measure common features in the side-lap region of adjacent
images to validate relative accuracy of the orthorectified images. Any areas identified as having horizontal
displacement across overlapping orthophoto boundaries will be examined for potential triangulation blunders or
surface model errors, and corrections are made if necessary to comply with the project requirements for
horizontal displacement. With horizontal accuracy requirements validated, the orthorectified imagery goes to
the mosaic creation stage.
RFP 030-25 2025 AERIAL PHOTOGRAPHY SERVICES | Technical Applications & Consulting
TAC has developed a proprietary method to address above ground features such as overpasses and bridges. The
initial step is described above for rectifying the image frames using the standard process. We then rectify the
above ground feature to a more general elevation plane from elevations that are derived from the feature in
question. TAC then finds the ideal image frame to best map the underground features in the image and then
seams in the bridge deck image rectified from the general elevation model. This method removes the majority
of the smears and offsets.
Image Quality and Tone Balancing: Digital orthophotography can exhibit tonal imbalances due to
factors such as sun angles, illumination, atmospheric conditions, and the timing of exposure, as well as image
characteristics and processing. TAC begins image quality and tone balancing by importing the raw camera data
into Capture One, allowing full rendering of imagery without losing valuable information in the data.
Brightness and contrast adjustments are performed on each flight strip and further adjustments are performed on
individual images until the whole collection matches throughout the mosaic. Verifications are performed to
ensure that information can still be derived on bright rooftops and dark shadows after the adjustments have been
applied. TAC strives to avoid acquiring imagery over large bodies of water during peak sun angle in order to
reduce sun flares. There are certain instances where sun flares cannot be avoided, and TAC will mitigate this by
adjusting seamlines around the affected images and applying different feathering options to the seamline to
blend in the data that cannot be seamed out.
Mosaicking: To ensure consistent tone across the project and address tile overlaps, we will mosaic the images
seamlessly. We will select the most advantageous areas of each photo to optimize color, tone, and contrast while
minimizing building lean and water glare. Mosaicking will combine automated tools and manual methods, with
seam lines manually placed to avoid issues in buildings, bridges, and other features. Manual editing will
QA/QC each tile for visible seam lines in water, warped bridges, and other anomalies affecting accuracy or
aesthetics.
TAC’s ASPRS-certified Photogrammetrists use a combination of Orthovista and Correlator3D for the creation
of the mosaic. Both software packages have the capability to automatically produce seamlines for each image
included in the mosaic, and algorithms are designed to reduce the chances of a seamline crossing through
elevated features. TAC’s photogrammetrists will review the seamlines throughout the mosaic and will manually
adjust the seamlines around particular structures. We will also reduce the localized color differences to produce
a high-quality seamless mosaic.
Positional Accuracy & Quality Control of Orthophotos: To ensure compliance with the 1.0-foot
accuracy requirement, TAC’s aircraft are equipped with TSO Certified Trimble AV 39 GNSS antennas,
providing centimeter precision with superior phase center repeatability. The Inertial Measurement Unit (IMU)
data installed with our camera systems is either recorded from the Applanix POS AV 410 or POS AV 510 at a
frequency rate of 200hz.
The airborne GNSS and IMU data collected during each mission will be used as the initial inputs in the post-
processing stage using Applanix PosPAC MMS version 9.1 software in tandem with their PP-RTX service. The
POSPac PP-RTX service is a cloud based global GNSS correction service which utilizes Trimbles RTX
technology to provide centimeter level post-processed positioning accuracy without base stations. Trimble RTX
technology utilizes data from a dedicated global network of tracking stations to compute corrections to satellite
orbit and time information as well as atmospheric delay models. PosPAC MMS will then compute a Smoothed
RFP 030-25 2025 AERIAL PHOTOGRAPHY SERVICES | Technical Applications & Consulting
Best Estimate Trajectory (SBET) file by averaging positions in time from a chronological sequence in forward
and reverse.
The processing and accuracy of the SBET file will then be reviewed by one of our photogrammetry
professionals. PosPAC MMS will generate graphs and statistical information of the SBET to determine whether
the solution adheres to the accuracy requirements. An Exterior Orientation (EO) file will be created from the
SBET solution providing positional information for each photo center collected for the project. That EO file will
then be used as the primary input in the aerial triangulation stage mentioned above.
An accuracy assessment will be performed by comparing the imagery in the final mosaic to surveyed photo-
identifiable points with respect to georeferenced ground positions of higher accuracy. Coordinate information
derived from the imagery will be input into a standard NSSDA report and will be compared to the survey points.
The NSSDA report provides statistical information of the root-mean-square error (RMSE) to estimate the
positional accuracy. RMSE is the square root of the average of the set of squared differences between the two
datasets. This report will determine whether the mosaic meets the 1.0-foot accuracy at the 95% confidence
level.
Metadata: All data produced by TAC will meet the Federal Geographic Data Committee’s (FGDC) Data
Content and Process Standards. The FGDC, which leads the National Spatial Data Infrastructure, has
established these standards to guide data content, classification, symbology, transfer, usability, and processes.
These guidelines cover everything from data collection and storage to the presentation of geospatial digital data.
Ownership of Completed Products: TAC acknowledges that all deliverables, imagery, documents,
reports, and information supplied by or to Pitkin County will remain or become the sole property of Pitkin
County. Subsequently, TAC guarantees these documents, deliverables, and information will not be released to
any third party, nor copyrighted.
Responses, Inquiries, and Correspondence: TAC acknowledges all responses, inquiries, or
correspondence related to or in reference to this request for bids, and all reports, charts, displays, schedules,
exhibits, and other documentation by the bidders and the contractor will become the property of the County

Getting paper or electronic copies
At any time, you may request from us a paper or electronic copy of any record provided or made
available electronically to you by us. For such copies, as long as you are an authorized user of
the DocuSign system you will have the ability to download and print any documents we send to
you through your DocuSign user account for a limited period of time (usually 30 days) after such
documents are first sent to you. After such time, if you wish for us to send you paper or
electronic copies of any such documents from our office to you, you may be charged a per-page
fee. You may request delivery of such paper or electronic copies from us by following the
procedure described below.
Withdrawing your consent
If you are an authorized DocuSign Account holder, you can decide to receive notices and
disclosures from us electronically, you may at any time change your mind and tell us that
thereafter you want to receive required notices and disclosures only in paper format. Described
below is the process for informing us of your decision to receive future notices and disclosure in
paper format and also how to withdraw your consent to receive notices and disclosures
electronically.
Consequences of changing your mind
If you elect to receive required notices and disclosures only in paper format, it will slow the
speed at which we can complete certain steps in transactions with you and delivering services to
you because we will need first to send the required notices or disclosures to you in paper format,
and then wait until we receive back from you your acknowledgment of your receipt of such
paper notices or disclosures. To indicate to us that you are changing your mind, you must
withdraw your consent using the DocuSign 'Withdraw Consent' form on the signing page of your
DocuSign account. This will indicate to us that you have withdrawn your consent to receive
required notices and disclosures electronically from us and you will no longer be able to use your
DocuSign user account to receive required notices and consents electronically from us or to sign
electronically documents from us.
All notices and disclosures will be sent to you electronically
Unless you tell us otherwise in accordance with the procedures described herein, we will provide
electronically to you through your DocuSign user account all required notices, disclosures,
authorizations, acknowledgments, and other documents that are required to be provided or made
available to you during the course of our relationship with you. To reduce the chance of you
inadvertently not receiving any notice or disclosure, we prefer to provide all of the required
notices and disclosures to you by the same method and to the same address that you have given
us. Thus, you can receive all the disclosures and notices electronically or in paper format through
the paper mail delivery system. If you do not agree with this process, please let us know as
described below. Please also see the paragraph immediately above that describes the
consequences of your electing not to receive delivery of the notices and disclosures
electronically from us.
