High resolution satellite image data now enable the generation of highly accurate and precise maps for cartographic purposes. This provides a valuable resource for urban planning, surveying and continual update of maps. Automatic feature extraction techniques can be used to yield GIS-ready information in a fraction the time necessary for conventional data capture. 
Multi-spectral satellite imagery enables the effective production of regional scale land cover maps. 
Stereo-scopic imagery now available from high and medium resolution satellites also enables the generation of Digital Elevation Models or DEMs which are suitable for map production at scales as low at 1:10,000.
