Location of public service facilities based on GIS

For "vast population and limited land" status in China, location of public service facilities, which is highly related to people\´s vital interest, is paid more attention to. The traditional public service facilities location method can be divided into continuous location method and discrete location method. However, there are much problems exist in the two methods. In order to improve the location method, a new analysis method based on GIS grid method is proposed in this paper. The new model combines the advantages of raster analysis and vector analysis. Location of Huanghua Middle School in Hebe province in China is taken as an instance to show the analysis process and result of the new method. As a result of the experiment, the case study confirms the feasibility of the new method.
