原始语种摘要: The main objective of the studywas to examine accuracies of DEMs (Digital Elevation Models) with differenttopographical structures generated by using the Unmanned Aerial Vehicle (UAV)point clouds. Two different terrains with flat and sloping topographicalstructures were selected for the study, and DEMs of these terrains weregenerated using eight interpolation techniques (Kriging, Natural Neighbor,Radial Basis Function Triangulation with Linear interpolation, NearestNeighbor, Invers Distance to a Power, Local Polynomial and Minimum Curvature).The accuracies of DEMs were tested by calculating the statistic methods withthe help of the control points obtained by land surveying techniques. At theend of the study, it was observed that in DEMs prepared for both flat (studyarea 1) and sloping...
