基于GeodataBase的CAD数据到GIS的解决方案

Study on Format Transformation from CAD to GIS on the Basis of GeodataBase

由于CAD系统与GIS在数据结构上存在着较大的差异,这使得其数据往往不能很好地满足GIS的要求。本文在分析目前CAD数据到GIS数据转换存在问题的基础上,利用ARCGIS的GeodataBase数据模型,探讨了基础地形图和规划CAD数据在转入GIS数据库中的逻辑组织、分层设计和属性设计等解决方案。但要从根本上解决CAD数据到GIS格式数据的转换的问题,还是需要一个“国家空间数据格式标准规范”的出台。

Data format of CAD often don’t accord with requirements of GIS. The paper analyzes the existent problem during data format transformation from CAD to GIS. And logic organization, layer and attribution design are studied when basal relief map and layout data with CAD data format are transformed into GIS by GeodataBase data model of ArcGIS .There, however, is still a urgent need for 'National Spatial Data Format Standards ' to frame in order to solve related problem ultimatly.
