Title Design and implementation of the shortest path analysis method based on MapX
Abstract
Network analysisis is an important aspect of the spatial analysis,and the shortest path analysis is the leading section.The shortest path problem in graph theory is the study of a classical algorithm problem.The purpose is to find the shortest path between two nodes in the diagram(composed by the nodes and paths).Through the shortest path analysis can solve a variety of complex issues, including mine rescue, etc.As used herein,
MapX is an ActiveX (OCX) technology-based programmable control.It uses the same map data formatas MapInfo Professional, and achieved the most function of MapInfo Professional.This article is based Mapx Technology,and using the Dijkstra algorithm achieving a more practical shortest path analysis through a series of studies.
