Comparative accuracy of DEMS from UAV and SRTMGL1 over the coast of Kuala Terengganu

Comparative accuracy of DEMS from UAV and SRTMGL1 over the coast of Kuala Terengganu

This paper presents a comparative accuracy of Digital Elevation Models (DEMs) derived from the Unmanned Aerial Vehicle (UAV) images and the Shuttle Radar Topography Mission Global 1 (SRTMGL1) included with the PALSAR Radiometrically Terrain Corrected (RTC) products. The accuracy of DEMs is computed...
