Automatic photogrammetric cartography

Some general remarks are made on digital drawings and the devices that have had to be created in order to produce truly complete automation of photogrammetric maps. Digital data acquisition systems of the autonomous long self-correcting type are described, as are certain adaptations performed on various types of optical mechanical plotters. Findings are given on the extreme modularity of automatic photogrammetry, and some forecasts are made on the phases of its future expansion.
