Gis-based Geographical Network Analysis

With the perpetual development of GIS technology and its integration with other correlative subject, The GIS application has made thoroughly changes. The one is that it spread form basic professional field to all the other social fields and become a basic tool for the spatial information process and application; The other is the GIS application ask for the spatial information process, combination and analysis, but the former is only for obtaining, managing, inquiring the spatial information. The users raise a higher claim for the analysis of the spatial location-relation and spatial correlation. The geographic network analysis is the main method for the research of the spatial location-relation and the spatial correlation. The claim for the geographic network analysis in real application is most common and insistent.Based on the research of relative achievements in China and other countries, we discuss a series of theories, algorithms and the models which has combination with the other function of GIS and realize some basic analysis models. Based on these research, we develop a system for geographic network analysis the on PC platform. The achievements can be summarized as follows:Collect, tidy up the relative achievements in China and other countries, discuss the concept and the theory system of the geographic network analysis.Study the basic model and algorithms of the geographic network analysis.Discuss the geographic network analysis combination with the other function of GIS.Based on the achievements above, the experimental system for geographic network analysis the on PC platform is developed.
