  • Generation of topographic terrain models utilizing synthetic aperture radar and surface level data
    Patent number: 5053778
    Abstract: Topographical terrain models are generated by digitally delineating the boundary of the region under investigation from data obtained from an airborne synthetic aperture radar image and surface elevation data concurrently acquired either from an airborne instrument or at ground level. A set of coregistered boundary maps thus generated are then digitally combined in three dimensinoal space with the acquired surface elevation data by means of image processing software stored in a digital computer. The method is particularly applicable for generating terrain models of flooded regions covered entirely or in part by foliage.
