Three research sites. (a–e) are the satellite views of the region in which the UAV images are taken. The central area of each (marked in green frame) is where the experiment is conducted. (b–f) are the distributions of GCPs and CPs measured by the RTK method on the corresponding DOMs of the experimental areas.
