CROSS VALIDATION ON THE EQUALITY OF UAV-BASED AND CONTOUR-BASED DEMS
UAV Photogrammetry Digital Elevation Model Topographic surveying Ground Control Points Accuracy analysis
2018/5/15
Unmanned Aerial Vehicles (UAV) have been widely used for Digital Elevation Model (DEM) generation in geographic applications. This paper proposes a novel framework of generating DEM from UAV images. I...
