【摘要】 本文以建立南京市专题地理信息库为例,较为详细地说明了如何利用现有的MapGis图形数据,在MapInfo系统中建立有别于基础信息库的专题信息库。信息库的地理编码遵循OpenGIS标准,数据模型建立借鉴了ARCGIS地理数据模型;并采用MapInfo流行的跨平台集成地图开发技术,建立了一个小型的应用系统,用于专题库的建立、应用、更新和维护。本应用系统的实用性较强,具有一定的市场开发前景。更多还原

【Abstract】 It is mentioned in detail that how to build thematic information base in Mapinfo using existing MapGis graphics data. The geographic coding follows OpenGIS criterion, the data model uses the ARCGIS geographic data model for reference, the Mapinfo integration map exploitation technique is used, a small application system is established, which can be used to build, apply, update thematic geographic information base.
