North Carolina Department of Transportation Photogrammetry Unit requires RFI submissions to be capable of supporting the following missions. 1) Aircraft and Sensor Requirements: a. UAVs with high-resolution LiDAR sensors for consistent point clouds and accurate colorization. b. Mobile platforms and handheld devices with LiDAR sensors for detailed data capture. c. Cameras for orthophoto creation. 2) Types of Missions: a. Pre-construction: Ground surface surveys and vectorization of roadway features. b. During construction: Temporal change detection, monitoring construction progress, measuring Cut and Fill volumes. c. Post-construction: Creating orthophotos and 3D reconstructions. 3) Post-Processing Needs: a. Manual and automated vectorization of 3D features. b. Temporal data analysis and generation of cut and fill volume reports. c. Image stitching, georeferencing, and generating 3D models and Digital Twins. d. Automatic extraction of roadway assets. e. Automatic extraction of break lines...
