Abstract : A method of extending geodetic control to geographical areas in which control is sparse or nonexistent makes use of unique combination of aerotriangulation and distance measuring technology. Aircraft or drones are flown over a designated area under control of a radial electronic navigation system. A second higher flying aircraft containing an accurately calibrated metric camera is controlled over the same area and aerial photographs are taken in sequence. Imagery includes both lower… CONTINUE READING
