The Design And Implementation Of Commercial Location System Based On GIS

With the development of society and economy,the distribution of urban commercial network is a significant part of overall design and planning of the city.Geographic Information System(GIS)has concerned about by more and more scholars and practitioners,and it has become a very popular subject.GIS has a huge advantage in the map visualization,spatial information retrieval and spatial analysis.At the same time,WebGIS is applied in more field and get more attention.Using GIS technology to manage the commercial branches not only enhances the efficiency of the operators' management stores and trading areas,but also has important significance for the rationalization of urban resource management.The structure of WebGIS system is described in this paper.The system uses the Browser/Server architecture,and uses JAVA language as the development language.In addition,it uses Geoserver to provide the map service,and uses Openlayers to realize operation in map.In the design of the database,the system adopts postgre SQL database and Post GIS as the system space database,and uses MySQL database as the attribute database.In this paper,the application of GIS in site selection is analyzed,expounds the basic theory of GIS,and analyze the functional requirements of the system.The basic theories of spatial database is described.In this system,it uses spatial database technology to store and operate features.It designs and develops the GIS commercial location system,realizes the acquisition function,shows the spatial data in system.At the same time,It develops plug-ins to operates map,analyzes the application of Openlayers.Finally,it develops a variety of spatial information query model.Compared with the traditional commercial stores management mode,the system put the store/trading areas information directly to the map.It shortens the work more time,and provides reliable guarantee for data accuracy.
