Ground Control Points in Drone Survey

Ground Control Points (GCPs) are defined as the points on the surface of the earth which help to georeference raster data such as satellite, aerial, or drone imagery. They help in high-precision drone mapping. GCPs reduce the margin of error from a scale of meters to centimeters.


They usually l...
