Some Automated Cartography Developments at the Defense Mapping Agency.
Abstract
The first steps toward an automated cartographic capability at DMA were taken to relieve the burden of manual scribing and drafting. Thus, the focus was on the automatic plotting of grids and projections, and later, on the digitization and tagging of line work, its digital manipulation, and its automatic plotting or scribing in a symbolized format. The present capability includes many photogrammetric, graphic, and hybrid techniques to capture cartographic and topographic information in a digital format directly from aerial photography or existing topographic maps. The emphasis today is upon the processing of such data into large data bases of elevations, cultural and natural features, and place names. The developments which will demand careful attention in the next decade are twofold. First, the structure and scope of the data bases will expand so that they may fully support topographic mapping, hydrographic charting, and special activity graphics. Second, systems will be developed to quickly exploit these data bases for the generation of both special and general purpose products in both graphic and digital formats. (Author)
