Aerial Image and LiDAR Collection/Processing - Manned Aircraft002
The work consists of acquiring large format, frame metric camera aerial imagery and airborne topographic LiDAR data using a manned platform at various altitudes above mean ground level. The aerial camera and topographic LiDAR systems must be integrated with on board Global Navigation Satellite System/Inertial Measurement Unit (GNSS/IMU) equipment to collect data for high accuracy sensor position and orientation determination. The work also includes flight and control plan preparation, image and LIDAR post processing, and certifying Reports for acquisition, position and orientation data, and LiDAR derived elevation products.
Land SurveyorP.L.S.P.L.S.
All work must be performed under the responsible charge of a North Carolina (NC) registered Professional Land Surveyor (PLS).  All Reports for acquisition, position and orientation data, and LiDAR derived elevation products must be certified by an NC PLS. The large format, frame metric camera shall be capable of acquiring frame imagery with the exposure station’s nadir Ground Sample Distance (GSD) generally between 0.10 foot and 0.45 foot with 60% forward overlap.  Deviations from this GSD range should be noted in firm's prequalification materials.  The topographic LiDAR system must be capable of acquiring and producing elevation data that meets the Quality Level 1 specifications as defined in the current USGS LiDAR Base Specification.  Submitted prequalification materials must include the following: proposed sub consultants; equipment list (planes, cameras, LiDAR systems, GNSS/IMU equipment, etc.) with technical data sheets for all proposed equipment;  base of operation for manned aircraft operations that includes airport code, airport name, city, and state;  and proposed software list (flight planning, post processing, LiDAR derived elevation product formats, etc.).  ​

Aerial Image Collection and Mapping Products W/UAS158
The work consists of using small format, frame non-metric camera imagery for generation of geospatial products to include image position and orientation determination, orthophotos, and elevation data. The work includes acquiring small format, frame aerial imagery with a mechanical shutter, non-metric camera on board an unmanned aerial system (UAS) platform at various altitudes above mean ground level. Primary focus is for Vertical Take Off/Landing (VTOL) UAS but fixed wing platforms are not precluded. For UAS operation, either a FAA Remote Pilot Certificate with an UAS rating under 14 CFR Part 107 (small UAS rule), section 44807 exemption of the FAA Reauthorization Act of 2018, or a Special Airworthiness Certificate (SAC) will be required. The firm must adhere to all current and future FAA and NC regulations regarding UAS operations including obtaining a NC Commercial UAS Operator Permit. The work also includes flight and control plan preparation, delivering geospatial products, and certifying Reports for acquisition, position and orientation data, orthophotos, and elevation data products.
Land SurveyorP.L.S.P.L.S.
All work must be performed under the responsible charge of a North Carolina (NC) registered Professional Land Surveyor (PLS). All Reports for acquisition, position and orientation data, orthophotos, and elevation data products must be certified by an NC PLS. The small format, frame non-metric camera must have a mechanical shutter and be capable of acquiring frame imagery with the exposure station’s nadir Ground Sample Distance (GSD) generally between 0.05 foot and 0.15 foot with 80% forward overlap at altitudes between 100 to 400 feet above mean ground level. Deviations from this GSD range should be noted in firm's prequalification materials. Submitted prequalification materials must include the following: proposed sub consultants; equipment list (UAS, cameras, GNSS/IMU equipment if applicable, etc.) with technical data sheets for all proposed equipment; proposed software list (flight planning, structure from motion photogrammetry, elevation data product formats, etc.) in use at the office that will perform these services; name, FAA license information, NCDOT Aviation Division UAS Operator Permit information, and amount of UAS operator experience for all proposed UAS pilots; general liability insurance information for UAS operations; and the location addresses for the base of operation for unmanned aircraft operations and the post-acquisition data processing of the offices being prequalified.

Aerial Mapping Control160
This work consists of establishing ground control for aerial mapping using Global Positioning System (GPS) and/or conventional surveying techniques. It involves placing and surveying well distributed photo-identifiable panels at control point locations throughout the project and submitting a Control Surveys Report. The Control Report must include both localized and State Plane Coordinates for each control point and shall be signed and sealed by the North Carolina Professional Land Surveyor (PLS).
Land SurveyorP.L.S.P.L.S.
Submit a list of GPS surveying equipment and a list of conventional surveying equipment. Submit an example of a GPS site calibration or site localization (this needs to show that you can GPS existing control points on a project and rotate, translate and scale your GPS data so that your GPS data agrees with the project control). The prequalification for discipline code 160 is only permitted in conjunction with prequalification for discipline code 158 or discipline code 159.​
