Geographic Information System of the traditional stand-alone mode , the service functions , application functions can no longer meet the needs of the users of the information age . The rapid development of the Internet , to GIS (Geographic Information System) industry has brought new opportunities for development , making the Internet Geographic Information System WebGIS applications increasingly cause for concern . With WebGIS, users can quickly and easily get the spatial data browsing , query and analysis capabilities . Currently, various GIS manufacturers introduced their respective development WebGIS platform . ArcGIS Server is a platform to create enterprise GIS applications , ESRI ArcGIS 9.0 Series new in the same industry first technology of GIS full-featured , enterprise-class server architecture . Based on this state-of-the-art platform , the development of the integrated planning of water resources in Wuhan information inquiry system , provides a great convenience for users to understand the spatial distribution of water resources conditions and access to water resources planning program . Distribution system consists of water resources in space , composed of three sub-systems of water resources data query and system management , query subsystem and data on water resources , including water resources survey , development and utilization of water demand forecasting , water conservation, water conservation, water supply forecast allocation of water resources , the embodiment of the eight functional modules, covering all aspects of water resources planning and management . First, the concept and theory of GIS and WebGIS overview analysis of the status quo and development trend of GIS and WebGIS , pointed out that the purpose and significance of the research . And then on the the ArcGIS Server WebGIS technical solutions , including ArcGIS Server functionality , features , architecture and its system configuration . With this development platform , to achieve a distributed enterprise-class WebGIS system . Finally , a detailed description of the of Wuhan integrated water resources planning information inquiry system architecture and the functions of the various subsystems , the realization of the development process of functional modules and related key technologies . The The the WebGIS system has developed applications in user units , with stable operation , easy maintenance management , powerful computing power advantages. , According to changes in user needs , the future can be easily expanded and change .
