Remotely Sensed Ground Control Points [PDF]
ISPRS - International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016 Accurate ground control is required to georeferenced airborne and spaceborne images. The production of ortho-photogrammetric data requires ground control that is traditionally provided as Ground Control Points (GCPs) by GNSS measurements in the field.

Terrestrial photogrammetry without ground control points
Earth Science Informatics, 2013 Terrestrial photogrammetry should be the survey technique of choice when updating large scale urban maps and GIS databases, where 3D data and attribute data are required. Its main drawback is the need for Ground Control Points (GCP) to reference the survey.
