Abstract

Digital as well as photographic satellite image data offer a high potential of topographic and thematic information. The paper discusses the application of such data for mapping purposes. For the compilation of conventionalTopographic Maps the requirements concerning the geometrical accuracy can easily be met for 1 : 50,000 or even 1 : 25,000. However, the interpretability of the features that are relevant for topography is often the critical factor. Only the Russian KWR-1000 data are suitable for mapping topographic features in 1 : 25,000. Main emphasis is laid on a new map type, theSatellite Image Map. The authors describe the satellite image mapping procedures developed at the Technical University of Berlin and applied in practice by FPK Consulting Engineers. Some related problems are discussed in details, eg mosaicking, merging of different types of data, and integration of graphical elements. An increase in cartographic applications of satellite remote sensing data is anticipated.
