Cartographic Raster Processing Programs at USAETL,
Abstract
The raster processing activities at USAETL have been concerned with both hardware and software development aimed at high-speed generation of topographic data base information and graphic map production. early work with raster digitizing techniques resulted in the development of the Cartographic Scanner/Plotter which provides a multi-resolution, rapid capability of digitizing or film plotting. Software to process these raster data has been developed for sequential computers as well as for the STARAN: associative array processor. Recently completed programs for the STARAN permit the processing of raster-scanned contour sheets, the semi-automatic determination and tagging of elevations for the contours, and INTERPOLATION OF THESE TAGGED CONTOURS INTO A UNIFORM GRID OF ELEVATIONS. Work has also been started on algorithm development for automatic detection of cartographically symbolized raster scan data. STRAPS programming improvements are under way which will provide expanded capabilities in the vector-to-raster and raster symbolization areas. The soon to be delivered Digital Laser Platemaker will provide a totally new capability to go directly from raster formatted data to press plates, eliminating the film preparation stages entirely. An inherent capability also exists in the laser platemaker to produce quick, self-developing proof plots and conventional film plots for back-up purposes, as well as to receive data via satellite for remote operations.
