[en] In this presentation we compare DEMs generated using terrestrial LIDAR and UAV data. The study site is a small agricultural watershed located near the region of Gembloux in Belgium. Terresttrial LiDAR data was collected using Trimble GX trought 14 scans. After correcting errors by using statistical approach, scans are meshed to generate a DEM of 1 m x 1 m resolution. UAV data was collected using the X100 UAV commercialized by gatewing. Data was processed in the open source MICMAC software to generate a DEM of 1 m x 1 m resolution. DEMs comparison to ground control points surveyed by RTK GPS, showed that DEM generated using terrestrial LiDAR data is the most precise with a RMSE of 4.9 cm compare to the DEM from UAV data which RMSE was 9.0 cm.
