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.

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.
