摘要： 针对在CAD环境中无法直接访问和编辑GIS系统中空间数据的问题，研究开源要素数据对象(FDO)空间数据访问引擎中的数据提供者(PDO Provider)的4个关键部分的实现技术：数据连接，数据模型之间的映射，坐标系统的识别以及数据的读写访问操作。设计并实现FDO Provider for SuperMap。结果表明，该系统可以使在AutoCAD Map 3D等CAD软件中直接访问和编辑国产主流的SuperMap GIS软件中的数据。

Abstract: Aiming at the problem that it can not access and edit spatial data of GIS system directly in CAD environment, the four key technologies of realizing open source Feature Data Objects(FDO) Provider are studied, including data connection, mapping between the data models, recognition of coordinate systems and read/write data access operation. It designs and implements FDO Provider for SuperMap. The results show the CAD software such as AutoCAD Map 3D has the capability to access and edit the SuperMap GIS data directly based on the system.
