Abstract:AS-llBX postprocessing involved coordinate transformation and interpolation of elevation data produced by the AS-llBX stereomapper. Associative array processing techniques were developed and programmed on the STARAN AAP to validate the timing estimates. These functions conform very well to associative array processing. The raster processing functions evaluated for this study were: registration mark detection, line separation, character recognition, line thinning, vectorization, skew correction, line break detection, line smoothing, and line symbol generation. A STARAN S-1000 can realize a two order of magnitude improvement over an IBM 360/40 for this application. The SMAC program effort was directed toward an evaluation of the effectiveness with which the STARAN AAP could perform various SMAC related search and matrix operations. STARAN's matrix arithmetic performance for large data fields will not offer an advantage to the SMAC program but the search operations will provide a great advantage.
