Stability of points and location change over time as illustrated: (a) Example of a surveyed point (id 40402278) at close distance (<2 m) and (b) Example of a surveyed point (id 63861648) at large distance (1938m). Location change can be either because of survey conditions, the accessibility of the terrain, and/or accuracy of GPS positioning. The background RGB imagery is obtained from “Map data ©2019 Google”.
