Distributed Geographic Mapping Using a Centralized DISSPLA-Based Mapping System and AUTOCAD PC Software

摘要

This paper describes procedures devised for transferring mapped information between a DISSPLA-based geographic mapping system on a centralized computer and an AUTOCAD system on a PC. The centralized mapping system is used as a repository for the large map data bases and to provide capabilities for drawing maps on various output devices including graphics terminals. The map data from any map drawn on the centralized system can be down-loaded to the PC. AUTOCAD is then used to view and edit the map and to add information. Final maps can be drawn using the AUTOCAD software or the AUTOCAD files can be sent to the centralized system to be included in the central data bases. These procedures allow us to take advantage of DISSPLA software, data management facilities, and graphical analytic functions available on the central system, while using the more interactive features available in AUTOCAD for viewing, entering, and editing the data. 2 figs.
