Abstract : Geographic Information Systems (GIS) contain functions to process the spatial and attribute data of a map. Digital Photogrammetric systems contain functions to aero-triangulate and visualize digital stereo imagery, rectify imagery, and create Digital Terrain Matrixes (DTM). Integration of GIS and processing on the most current stero imagery. Such photogrammetric GIS technology enables more reliable imagery measurements than two-dimensional GIS technology which only allows horizontal feature extraction from a single image. The single image usually retains geometric distortions from its original exposure complicating the mensuration and delineation of the objects in the map. The U.S. Army Topographic Engineering Center (TEC) has assembled a fully integrated digital image-based mapping system called the Terrain Information Extraction System (TIES). This paper evaluates the photogrammetric GIS, technology on the TIES.
