The Building of Topologic Relationship and Analysis of Shortest Path Based on MapX
Zhao Dong-qing · Surveying and Mapping of Geology and Mineral Resources · 2004
The building of topologic relationship is the key to analysis of shortest path. For the secondary developers based on MapX, the analysis of shortest path is a difficulty because MapX does not support the topologic relationship of spatial data. This paper discusses a series of questions as to the preprocessing of route data, automatic Cut-line and the building of topologic relationship. Based on those, the analysis of shortest path is accomplished and the problem is resolved successfully.
