摘要
为解决将其他格式的地理文件导入Trans CAD中构建路网后存在的连通性问题,在总结路网中虚连接常见类型的基础上,设计和实现了基于GISDK的路网虚连接的修正方法。利用GISDK编程在修正后的路网上进行最短路径应用分析,验证了所提出方法的有效性。
It is common to build a road network by importing geographic files in various formats into Trans CAD in engineering practice,which,however,might cause connectivity problems. In this paper,some common types of virtual connection in road network are summarized,and a GISDK-based method of fixing virtual connection is designed and implemented. The validity of the proposed method is verified by applying to the modified road network the program compiled with GISDK for the shortest path analysis.
