Aim. Determination of the elements of external spatial orientation of the surveying systems at the moment of image acquisition is the fundamental task in photogrammetry. Principally, this problem is solving in two ways. The first way is direct positioning and measuring of directions of camera optical axis in the geodetic space with the help of GNSS/INS equipment.
referencing of large-scale aerial images
Objective. Permanent growth of the volume of remote-obtained information about location sets have challenged tasks for scientists and experts concerning quality of its processing in terms of efficiency, completeness, subject, and geometrical accuracy. The important precondition for performance of the tasks is to supply reference information for the images.
