| Abstract: | This system, by making use of the digitizing table and the sterocomparator for data input,designs a simplestructure for the topographic data, and solves such problems as blunder detection, on-line editing, andgraphic monitoring. So, this system can provide the Digital Mapping System with correct and integrated da-ta. |
