Using GCPs

A Ground Control Point (GCP) is a characteristic point whose coordinates are known. Their coordinates have been measured with traditional surveying methods or have been obtained by other sources (LiDAR, older maps of the area, Web Map Service). GCPs are used to georeference a project and reduce the noise.
