| Abstract: | Airphotos have been used for topographic survey since the Twenties. The “European Space Agency” (ESA), the “Deutsche Forschungs-
und Versuchsanstalt für Luft- und Raumfahrt” (DFVLR) and “Carl Zeiss” have modified this successful technique for spacecraft
and recently have tested the system over four continents. Each of these satellite photos covers a region of 189×189 km to
the scale of 1∶800000 and may be enlarged to 1∶250000 or 1∶100000. Between the altitudes of 200 and 300 km, mapmaking or-revision
seems to be economic in zones or in countries, where existing maps are of minor quality or outdated. In this paper, examples
from deserts and semideserts in the Sudan are presented. |
