ArcSDE在基础地理信息数据库更新中的应用

在国家1∶50 000地形数据库动态更新过程中,笔者通过总结"十二五"期间传统地形数据库的更新方法,提出了基于ArcSDE的、支持多用户分布式在线整理、编辑地形数据库的新方法。本文以朝阳市作为研究对象,通过ArcSDE构建支持集中管理、多用户同步编辑和更新的数据库处理平台,完成了2015年朝阳市1∶50 000地形数据库的更新工作,与以往传统更新方法相比,该方法节省作业时间,提高了工作效率。

The Application of ArcSDE in the Fundamental Geographic Information Database Updating

Through participating the dynamic updating project of 1∶50 000 terrain database of the updating of national fundamental ge-ographic information database and analyzing the general method of terrain database updating in"The Twelfth Five-Year Guideline”, the author proposes a new method based on ArcSDE, which supports multi-user distributed editing terrain database online.Then, taking Chaoyang as the research object, this paper constructs terrain database processing platform which includes centralized manage-ment, multi-user editing and updating by ArcSDE to complete the 2015 work of dynamic updating project of 1∶50 000 terrain data-base in Chaoyang City.Compared with the traditional updating method, this method can save the working time and improve working efficiency.
