摘要
数据更新的质量控制一直是当前GIS研究的难点之一,鉴于地籍管理中特殊的空间拓扑关系,本文探讨利用空间拓扑关系的约束来控制和自动更新地籍数据库,通过理论和实例分析,证实了这种思路的有效性和实用性.
Quality control of data update is a nodus of GIS. According to the specialty of topological relations of spatial objects of CIS, the author illustrates how to control and automatically update database of CIS and gives an example to prove its practicability and efficiency.
