DFAD PLUS System Development

Abstract:

Between 1987 and 1992, ERDAS, Inc., and Gilmore Aerospace Corporation developed a prototype expert system for the update of Digital Feature Analysis Data DFAD based on multispectral imagery and a number of commonly available Geographic Information System GIS layers. A method was developed by which ERDAS GIS Modeling tools were used to simulate and validate decision rules that were then downloaded to the Ada Based Expert System Testbed ABEST for execution. ERDAS developed data acquisition programs for acceptance of DFAD point, line and polygon data and conversion of DFAD into the ERDAS internal polygon file structure. The information is subsequently gridded to produce a raster GIS layer. ERDAS also made improvements to a semi-automatic Digital Terrain Elevation Data DTED loader.
