Photoimages for map bases

March 1, 1973

Maps with aerial photograph image bases have gained wide popularity. The orthophotomap presents an abundance of ground detail and information that cannot be shown on a line map with standard cartographic symbols. In preparing a map base covering areas of little relief, the imagery is fitted to map control with a conventional rectifier, but for areas of significant relief, the photographs are reproduced in an  orthophotoscope to remove the effects of both camera tilt and terrain relief.
