Photogrammetric Processing of UAV Imagery: Checking DTM

Abstract

The fixed-wing EPP-FPV Unmanned Aerial Vehicle (UAV) with mounted digital camera Canon S100 was used as a platform for images acquisition. Up-to-date the application of such means has increased significantly. Implemented features are low-cost, mobile and simple. Digital photogrammetric software Lisa has been used for UAV images processing and area mapping. High correctness of digital terrain model is required for the generating standard mapping products, as is orthophoto map. The quality of mapping products mainly depends on flight height, camera characteristics and ground control point's accuracy. Applying appropriate technique for digital elevation model checking, DEM errors has been determined.
