The aerial mapping division follows the same established workflow as used with conventional aerial mapping. The UAV is a great technology for smaller geographic areas, where traditional aerial mapping could be cost prohibitive. The UAV can provide TxDOT with high resolution orthoimagery (1.2cm pixel resolution) and is well-suited to flying projects on a repeating basis (weekly, monthly) for planning, change detection, and project management. G&AI’s UAVs use medium format digital metric cameras for photogrammetry and state-of-the-art airborne LiDAR sensors for aerial LiDAR data collection with similar accuracies seen with manned flights. The G&AI fleet of UAV systems includes Alpha Unmanned Systems A-900 helicopter platform (heavy lift drone), multiple DJI M-300 multi-rotor systems, and a Harris Aerial – Carrier H6 Hybrid EFI (heavy lift drone). As with conventional aerial mapping projects, all photogrammetry projects will be overseen by an American Society of Photogrammetry and Remote Sensing (ASPRS) Certified Photogrammetrist and all aerial LiDAR projects will be over seen by an ASPRS Certified Mapping Scientist in LiDAR.
