UAV Aerial Mapping

Aerial imagery from RTK-equipped UAVs, combined with GNSS-surveyed ground control points (GCPs), to produce orthophotos, DSM/DTM and reality-mesh 3D models. Suited to sites from 5 ha up to several thousand hectares.

Typical specifications [x confirm with actual practice]

Item Value
Platforms DJI M350 RTK + Zenmuse P1; Mavic 3 Enterprise
GSD 1.5–5 cm/pixel depending on flight altitude
Overlap Forward 75–80 %, side 65–70 %
Control GCPs + independent checkpoints, GNSS RTK
Software Agisoft Metashape, DJI Terra

Deliverables

  • Orthophoto in GeoTIFF/ECW (VN-2000), tiled for WebGIS.
  • DSM, DTM, contour lines.
  • 3D mesh (OBJ, OSGB, 3D Tiles), photogrammetric point cloud (LAS).
  • Accuracy report with XY/Z RMSE on checkpoints.
