A computer program provides for automated generation of maps from data acquired via C-band interferometric synthetic-aperture radar (IFSAR). The program reads in height, radar-brightness, and correlation data generated by IFSAR processors and computes a series of image features to be used in classifying terrain. Correlations between IFSAR channels are used to estimate new terrain-classification parameters. Classification is accomplished by use of a Bayesian classifier and is followed by spatial editing of terrain classes. Next, various additional layers of data (pertaining to IFSAR height error, shaded relief, drainage, and mountains) are computed and the data are projected into the universal transverse Mercator coordinate system. The results of the foregoing process are then turned into cartographic products with the help of commercially available software.

This program was written by Ernesto Rodriguez, Thierry Michel, Jan Martin, and Bijan Houshmand of Caltech for NASA's Jet Propulsion Laboratory. NPO-20325
