Paper Abstract

Satellite programs of the 1980's such as Landsat-5, Shuttle/Spacelab and SPOT will produce a variety of image data recorded by film cameras, electro-optical sensors and synthetic aperture radars which can be used for mapping tasks. Efforts will focus on producing topographic, thematic and image maps at scales of 1:25,000 to 1:100,000. Studies to date indicate that spatial resolution and geometric fidelity are the most important factors controlling the completeness of detail and accuracy to which terrain coordinates can be derived. As most satellite systems do not currently provide both spacecraft position and attitude data to sufficient accuracies for cartographic purposes, terrain coordinates must be derived from image measurements referenced to ground control. Of the satellite systems currently planned for operation during the next two years, the Large Format Camera and Metric Camera employed on board the Shuttle will provide photographs with resolution and geometric characteristics compatible with map products at 1:50,000 scale. SPOT, which will produce both 10m panchromatic and 20m multispectral data in stereo formats, will provide digital data of the Earth suitable for cartographic applications.
