PROJECT DESCRIPTION
SCOPE OF WORK
The following Tasks are the detailed scope of work. The Vendor will be responsible for delivery of these
tasks for the area of Moore County that includes all the parcels in Moore County, now referred to area of
interest from this point forward. Full tiles to be delivered of any tile that is delivered for the area of
interest. Moore County reserves the right to modify and further develop project specifications with the
Vendor. Any modifications to the State Standard or other terms of the Agreement requested by a Vendor
must be submitted to Moore County for consideration together with a written justification for the
requested change. Changes shall be permitted only upon approval of Moore County, and if evidenced in
writing by the Vendor and Moore County.
The Vendor shall acquire new high-resolution natural color digital aerial imagery with airborne GNSS-
IMU control and ground surveyed control to support orthorectification of either four-inch (4") or six-inch
(6") pixel resolution 4-band digital orthoimagery depending on cost. The County is also interested in an
option to add on oblique photography, if possible, at the same resolution. If the Vendor does not capture
oblique photography as part of their service, it is ok to just submit the proposal for the orthoimagery as
this is our primary need. If the Vendor captures any other data during flight as an optional add-on, the
vendor should provide a description of the service and qualifications for the county's consideration.
Data acquisition will be consistent across the acquisition area with south to north oriented flight lines
utilizing large format aerial digital camera systems and conforming to the North Carolina Technical
Specifications for Digital Orthophoto Base Mapping, Adopted December 2014 by the Secretary of State
(the State Standard). All technical requirements referred to in this document must adhere to the
specifications set forth in the State Standard unless otherwise noted in this Scope of Work. Below is a
link to this standard:
https://it.nc.gov/documents/files/north-carolina-technical-specifications-digital-orthophoto-base-
mapping/download?attachment
The Vendor will be required to share ground control coordinates, AT data, exploitation images, look up
tables (LUTs) and any useful data along project boundary regions. This requirement will be applicable to
all Tasks.
Task 1: Flight Planning, North Carolina Validation Range Accepted and Preferred, Camera
Systems Acceptance, Control Surveys, and Quality Assurance/Quality Control (QA/QC)
The purpose of this task is to perform all necessary work to complete pre-flight planning, validation
range processing, digital camera systems acceptance, control surveys, QA/QC, and reporting in
accordance with the State Standard, this Scope of Work, and other project specific standards that may be
mutually developed during scoping and execution of this project.
Control and Check Points
The Vendor shall plan and survey sufficient ground control to use with airborne GNSS-IMU control to
produce orthoimagery tiles that meets American Society for Photogrammetry and Remote Sensing
3

(ASPRS) horizontal accuracy for either 4-inch 6-inch orthophotos, 1"=100' scale planimetric data with a
limiting RMSE of 1.0 feet in each X and Y. The NC Geodetic Survey can provide information on
existing government control monuments. If additional controls are required, the Vendor is to indicate the
location of the necessary additional control and describe how that control will be established.
Based on the number of aerotriangulation (AT) Blocks per assigned area of interest, the Vendor shall
select a defined number of previous project points not used for control to be used as independent check
points for quality review:
* 1 AT Block: 30 checkpoints evenly distributed across the entire area of interest with a
minimum of 3 per county)
* 2 AT Blocks: 40 checkpoints (20 checkpoints per AT Block evenly distributed with a
minimum of 2 per county)
* 3 AT Blocks: 60 checkpoints (20 checkpoints per AT Block evenly distributed with a
minimum of 2 per county)
The Vendor shall use their professional judgement to determine whether coordinates from previous state
project GCP are sufficient or if they must be re-occupied. The Vendor shall be responsible for recovering
the previous project state GCP and painting or setting panels as applicable. In the event the Vendor is
unable to recover any of the previous state project GCP, then the vendor shall report such and establish
and survey a new independent checkpoint in the same vicinity as the points that could not be recovered.
The Vendor is expected to identify and comply with applicable specifications set forth in the State
Standard and this Scope of Work that cover these work phases. Specific sub-tasks that the Vendor must
address include, but are not limited to, the following:

documentation, adherence to standard operating procedures, specific measures and
observations, acknowledgment from responsible officer of conclusions, demonstrated
application of pre-flight specifications and settings that adhere to or meet minimum
recommendation including TDI settings, and overall summary of conclusions for performing
or not performing reflights.
Task 3: GNSS-IMU Post Processing Aerotriangulation, DEM Update, Orthoimagery Product
Generation, Processing Quality Assurance/Quality Control (QA/QC), and Reporting (CONSIDER
additional requirements for true ortho)
The purpose of this task is to perform all necessary work to complete airborne GNSS-IMU post
processing, aerotriangulation, orthoimagery product generation, QA/QC, and reporting defined by the
Area of interest in accordance with the State Standard, this Scope of Work, and other project specific
standards that may be mutually developed during scoping and execution of this project. The previous
project ground control points (GCP) for the project area shall be used by each Vendor as independent
check points for quality review. The Vendor shall be responsible for recovering the previous project
GCP and painting or setting panels as applicable. In the event the vendor is unable to recover any of the
previous project GCP, then the vendor shall report such and establish and survey a new independent
checkpoint in the same vicinity as the points that could not be recovered. Prior to aerotriangulation and
after approval of the vendor flight and control plan. The vendor is expected to use their judgment
regarding inclusion in the aerotriangulation adjustment.
3.1. Perform airborne GNSS-IMU post processing. For the push broom camera, exposure and time
of exposure shall be treated as Pseudo Exposures spaced at a nominal 200-foot spacing not to
exceed 210 feet.
3.2. Perform aerotriangulation using ground survey control and airborne GNSS-IMU control.
3.2.1. Manual or auto correlated pass and tie point image measurement is acceptable. The
Vendor will have image measurements for frame sensors at the 9 traditional Von Gruber
locations per image. In regions of frame imagery where auto-correlated image measurements
are not produced at the 9 traditional Von Gruber locations per image as a minimum, the
Vendor shall make every effort to manually measure pass or tie points. For pushbroom
sensors, pass points shall be located along each strip at intervals corresponding to, at a
minimum, half of the nadir imaging array format width. Additionally, tie points in
overlapping strips shall be measured at the same interval. If the Vendor elects to use
photogrammetrically derived coordinates as "tie control points" between adjacent
aerotriangulation blocks, then these points shall be manually measured on the ground
surface, preferably at a photo-identifiable feature.
3.3. The Vendor will review and update the best available elevation data (as needed) at a density level
sufficient to accurately represent the shape of the ground to produce orthoimagery free of
distortions due to terrain, and that meets the required orthophoto accuracy standards. The
Vendors should work with the Project Team to identify best available elevation data sources.
3.4. Following approval of GNSS-IMU Post Processing & Aerotriangulation Reports, the Vendor
will perform orthorectification using exploitation imagery, adjusted exterior orientation from
aerotriangulation and updated (as needed) DEM elevation data to produce orthoimagery.
7

3.5. The Vendor will develop additional data requirements, input, and workflows for DTM elevated
breakline features, point cloud data or a raster DEM that will meet orthophoto accuracy standards
and requirements for removing occlusion to develop true orthoimagery.
Task 4: Digital Imagery Quality Assurance/Quality Control (QA/QC), Product Delivery and Data
Acceptance Requirements
The Vendor will be required to deliver an image product that satisfies the specification as defined by the
State Standard, this Scope of Work, and other project specific standards that may be mutually developed
during scoping and execution of this project. The Vendor will ultimately provide written and visual
documentation that provides tangible evidence of said compliance in a signed and sealed document
during final delivery in Task 5.3.
The Vendor will be required to perform the following:
1.1. The Vendor will be required to perform a macro level quality review to demonstrate adequate
seamless orthoimagery that is visually consistent and meets the pilot area that satisfies the
requirements of the State Standard. The Vendor will be required to perform a detailed quality
review of each ortho-rectified tile and correct image distortions due to seam lines, elevation data,
blurring, or other artifacts caused by the orthorectification process. Any tile with a 4th band that is
not consistent with the RGB bands will require redelivery.
1.2. The Vendor will submit one TIFF file for all tiles assigned to a county delivery order. The data
must meet pre-defined acceptance criteria guidelines. The Vendor will deliver one
uncompressed GeoTIFF formatted ortho-rectified image per County as defined in the area of
interest referenced to the North Carolina State Plane Coordinate System, North American Datum
NAD83 (2011) epoch 2010.0 including a world file, GeoTIFF header version 6.0 as required by
the State Standard, and that adheres to the per tile naming convention defined in Task 5.3.
1.3. The vendors will also deliver digital seamlines polygons to Moore County for upload into the
image service provider. The coverage area will be defined as the maximum extent of all tiles
required for that delivery order. The attributes for each submittal will include a vendor
number/area of interest field (StdAreaID) defined as a text format. Seamlines may be submitted
for the entire area of interest, but they must be re-submitted in entirety if seamlines are adjusted
for future deliveries.
Task 4 Deliverables:
* GeoTIFF file
* Seamline polygons
Task 5: Quality Review Resolutions
Imagery will be subject to two Levels of quality review exclusive of the Vendor's own internal measures
as follows:
Level 1: Moore County will contract the Vendor with the task of providing tangible documentation that
the product satisfies the requirements of the State Standard and to demonstrate that a macro level quality
review has been performed.
8

Level 2: Moore County will perform a visual quality control of the tiles. Moore County will submit
quality issues submittals to the Vendor for remediation. Moore County will perform distribution of the
final image products.
Procedures and criteria for QA/QC for evaluating the quality of images will be performed per the State
Standard, this Scope of Work, and other project specific standards that may be mutually developed
during scoping and execution of this project.
5.1. The Vendor will be tasked with evaluating submitted issues for all Levels and posting resolutions
in a timely manner, with resolutions in the form of the GeoTIFF product or demonstrate why
resolutions are not practical or within scope. If it is determined issues have not been addressed
or additional issues have been created, the Vendor will rectify those issues and submit during
final delivery.
5.2. Moore County will perform validation of the data to confirm completeness. The Vendor will
perform reprocessing for any orthoimagery tiles and data that do not meet requirements.
1. One set of uncompressed 4-band (RBGIR) GeoTIFF formatted ortho-rectified imagery tiles
referenced to the North Carolina State Plane Coordinate System, North American Datum
NAD83 (2011) including a world file, GeoTIFF 6.0 header and that adheres to a naming
convention per tile per County and following the example where the filenaming convention
follow demonstrates the earliest and latest date of acquisition per county
OC6i0_37_000_12345678_20120215_0305R0 where the most recent date is appended to the
earliest date (Current Prefix_Imagename_8 Digit start date YYYYMMDD_4 Digit finish
month and date MMDD Revision Number). In this example, February 15 is date of first
acquisition and March 5 is the latest.
2. One polygon shapefile representing all edits made by the vendor during the Level 2 Quality
Review outlined previously in Task 5. The locations in this shapefile will be analyzed on the
delivered imagery tiles by Moore County to ensure consistency between all four bands of
imagery.
5.3 Deliver a single FGDC compliant metadata record for imagery per area of interest per one file
format each in .XML and .txt that will meet the requirements at time of the final delivery order.
The Vendor shall perform preliminary QC of each record using the USGS MP Parser online tool
http://geo-nsdi.er.usgs.gov/validation/ and provide report documentation of adherence to the
standard. Moore County will perform quality review of the metadata file and reject if not found
to comply with the State Standard and/or pass testing through the USGS validation tool.
5.4 Deliver one fully attributed seamlines polygon shapefile of the Vendor's area of interest at time of
the final delivery order. The file shall be considered representative of all final seamline
adjustments. The seamlines will be aligned with the vendor's contracted tiles that include
populated attributes for only vendor ID, flight line ID, frame number ID, and acquisition date.
Task 5 Deliverables:
* Digital data (GeoTIFF files, DEM, Seamline polygons)
* Metadata
* Level 2 Quality Review corrections
* Horizontal corrections
Task 6: Project Closeout and Project Documentation
The purpose of this task is to list the deliverables to facilitate project closeout. In addition, this task
