This paper describes an automatic system for classifying and delineating terrain features in aerial photography. Recognition algorithms are based upon sharing the burden of image shape detection between a special film scanner and a general-purpose computer. Classification is based upon "common sense" characteristics of terrain categories, implemented by local shape recognition and binary decision criteria. Procedures are described and system implications discussed.
