Realistic 3D models of terrain or objects with accurate geodetic references can serve as the basis for developing a digital twin of a city. By linking reference points to the terrain in the required coordinate system, the resulting models have a colossal amount of accurate geodetic data. The model is built by identifying terrain objects on various frames of a digital camera installed on board the aircraft. In the process of shooting, get nadir and perspective shots
