中文摘要：
从GIS和CAD两种数据模型出发，提出基于Check Out/In的数据更新机制，为了充分利用CAD制图功能，在CAD中将新测数据插入到更新区域，然后写入子数据库，同时父数据库自动检测并做出响应。实际应用证明该研究成果能提高基础地理数据库的更新速度。
英文摘要：
Today, urban development is so rapid that the updated cycle of geodatabase should be shortened. After studying existing results based on GIS and CAD models, the updating system based on Check Out/In is put forward. By use of the CAD＇ s mapping functions fully, new surveyed data are inserted into the area to be updated, and saved to a sub -geodatabase. At the same time, its parent geodatabase will detect it and respond to automaticly. Experimental results certify that this method can update the city＇s fundamental geodatabase more rapidly.
