Methodology for Digital Processing of Geographic and Cartographic Data

摘要

The application of computer technology to cartography has produced numerous digital techniques that are employed in a wide variety of independent automated and semi-automated cartographic systems. These systems are used by government agencies and private industry for compiling maps and charts. The US Army Engineer Topographic Laboratories (USAETL) is testing and evaluating a subset of available off-the-shelf and state-of-the-art R&D digital techniques in an Experimental Geo-Cartographic Laboratory System and developing a methodology for automated map and chart production. The methodology, which is based upon geographic and cartographic principles, is defined and outlined in this paper along with early experimental results derived from the integration of key hardware/software systems.
