Collection of computer programs processes image data obtained by synthetic-aperture radar (SAR) along with measurements of water levels taken at selected points on ground to generate three-dimensional maps of surveyed terrain. Information in maps presented in variety of useful ways suited to study of such phenomena as flooding, damage caused by floods, flow of nutrients from forests to river and marine ecosystems, and effects of subsidence of ground or of rising sea levels.
