In this study, the effect of the height difference, geometry, and number of GCPs on the positional accuracy of point cloud was investigated in UAV photogrammetry. It has been determined that the topographic change of the study area, the geometric structure of GCPs, and the distance between GCPs are the most important factors in GCP network design. It was observed that the GCP network design is more important than the number of GCPs in the UAV Photogrammetry method to increase the positional accuracy.
