The article is dedicated to the 120th anniversary of the birth of Mikhail Dmitrievich Konshin, an outstanding Russian scientist, one of the founders of the Soviet photogrammetric school; his name is inextricably linked with the history of development of Russian aerial surveying; twice awarded the State Prize, Honored Worker of Science and Technology of Russia, Doctor of Technical Sciences, Professor. Of particular importance for development of the theory of the said science was his work "Photogrammetric processing of images with transformed bundles". It brought the domestic photogrammetric instrumentation to the forefront, ahead of foreign instrument developments based on schemes with similar design links. The theory of M. D. Konshin was later applied and developed by other scientists and contributed to creating in the mid-1950s domestic universal stereophotogrammetric devices for processing aerial photographs obtained by cameras with arbitrary focal length – the Romanovsky stereoprojector and Drobyshev stereograph, which was especially important for mapping the territory of the USSR
