Study on GIS Framework and Spatial Data Mining Model of China Highway Natural Regionalization
The main task of highway natural regionalization is to reveal the regional differences of the natural environment of highway engineering, and provide scientific basis for highway construction decision. To have a quantitative and automatic study on China Highway Natural Regionalization, obtain scientific and objective regionalization conclusion, we studied the framework, spatial data mining model and development methods of China Highway Natural Regionalization GIS (HR-GIS). This paper studied integration method and framework of HR-GIS according to the guideline and methods of the research of Natural Regionalization for China Highway. Rased on object-rational model, the spatial database has been built for massive data management. The spatial data mining methods were put forward to accomplish quantitative calculation of environmental indices. Using ArcGIS Engine technology, the HR-GIS has been developed and completed, and it has the functions of spatial analysis and information inquiry of natural regionalization.
