| Abstract: | This paper introduces general concept of map data base and function of MDBMS(Map data base management system),analyses the basic character of map space information. The map space information, conitain position information, attribute information and topology structure. Based on the charcter of map space information writer constructs a logic data Sturcture of map space information. Because position and attribute information Changes individally with time, the position information and attribute information shoud be stored and operated individually in MDBMS. In this paper, according to the cartographic cover theory, writer introduces the best storage structure of map information. In MDBMS, map information is operated hierarchally. Every hierarchy contains point, line and area. attribute., In same field, we can make choice of geographic feature. The geographic feature is stored hierarchally in data base. In this paper, according to the character of position and attribute information, writer narrates a detail projection to build MDBMS by extending REBMS, researchs adminetrative attribute information.and programs a special admtnistrative software that operates position information. In other end, this paper introduces data strorage operation in detail. At last,this paper introduces user interactive query and data base safe-keeping. |
