Learn what GCPs are, how they are used to georeference data, and what software can be used to collect and process them. Find out the requirements, features, and applications of GCPs in various fields such as land survey, mapping, and engineering.
Ground control points (GCPs) are locations that we can track with high precision and accuracy between the targeted object and a selection of our photos. We can use these to provide “exact” real world coordinates to our reconstructed models, as well as to determine the accuracy and impact of processing parameters.
