Paper Abstract

A computer-assisted photo interpretation research (CAPIR) system has been developed at the U.S. Army Engineer Topographic Laboratories (ETL), Fort Belvoir, Virginia. The system is based around the APPS-IV analytical plotter, a photogrammetric restitution device that was designed and developed by Autometric specifically for interactive, computerized data collection activities involving high-resolution, stereo aerial photographs. The APPS-IV is ideally suited for feature analysis and feature extraction, the primary functions of a photo interpreter. The APPS-IV is interfaced with a minicomputer and a geographic information system called AUTOGIS. The AUTOGIS software provides the tools required to collect or update digital data using an APPS-IV, construct and maintain a geographic data base, and analyze or display the contents of the data base. Although the CAPIR system is fully functional at this time, considerable enhancements are planned for the future.
