What are passport points used for?
"In photogrammetry and remote sensing, control points (also known as reference points, ground control points (GCPs), or fixed points) are used to determine the orientation elements of a survey image. These are points in the terrain whose position is known in a corresponding (terrain) coordinate system and which are clearly identifiable in an aerial or satellite image." (Wikipedia) Control points are also used in surveying with drones/UAVs (Unmanned Aerial Vehicles). GCPs significantly improve the accuracy of orthophotos and drone maps.
The control points can also be used as adjustment points for the installation of machines.
