GIS中拓扑关系的建立与更新
|
摘要
拓扑关系是地理信息系统(GIS)中一类重要的空间关系。拓扑关系一直是GIS研究的课题之一。当前拓扑关系的建立方法多数并不完善，不能胜任大数据量和一些复杂情况的要求。另外，在拓扑关系的更新问题上，尚缺乏能够进行局部拓扑更新的方法。
本论文重点研究了拓扑关系的建立及其更新问题，一方面对传统的拓扑建立进行了必要的改进，使其具有高效性和通用性；另一方面，提出了一套数据编辑时进行拓扑关系局部更新的方法以减少拓扑重构的时间。
Topological relations are important spatial relations in Geographical Information System (GIS). Topology is one of the subjects studied in GIS all the while. Most methods today to build topology are not perfect because of their inefficiency in dealing with huge amount of data and complex cases. Moreover,there are few ways to update topology partially in case of data modification.
This paper studies the two problems above. On one hand some necessary improvements are made in existing topology building methods for its higher efficiency and adaptability. On the other hand,a set of methods of updating topology partially are proposed which can reduce the time of rebuilding topology greatly in editing data.
