“智慧余杭”基础地理信息数据库更新方案研究

Research on the updating scheme of “Wisdom Yuhang” basic geographic information database

文中结合“智慧余杭”基础地理信息数据库更新方案实际,研究实现由传统的基于图幅更新到面向要素的更新模式的转变,实现对全区基础地理信息数据库的更新。探索了一种定期更新和动态更新相结合的工作模式,有效缩短了更新时间并提高了更新效率。

In this paper, combining the reality of the "Wisdom Yuhang" basic geographic information database updating scheme, the transformation from traditional map-based updating to element-oriented updating mode was studied and realized, and the updating of the regional basic geographic information database was realized. The work mode which combined the regular update with dynamic update was explored, which could effectively shorten the update time and improve the update efficiency.
