Abstract

New developments can be expected in the realm of the cartography and regional analysis from the informations of high resolution earth observation satellites. This improvement of the resolution, however, will not be sufficient in the near future to allow a topographic mapping from spaceborne informations at great to medium scales. But the thematic cartography and the actualization of the topographic maps, as far as the land use is concerned, will be greatly improved by the multitemporal and multispectral capacities of these high resolution devices. In the field of the regional analysis, these types of sensors will be most efficient in the recognition of landscape patterns ; the size of the pixel, indeed, and the lack of stereoscopy in the past were limiting factors to the textural analysis. Finally, new important opportunities for the regional planning and reconversion analysis result from the application of high resolution spaceborne information systems.
