For Flood Control System Webgis Technology, Research And Realization

The application of Internet Technique in CIS field produces WebGIS Technique. With the development of Internet Technique, the WebGIS Technique grows. Using Internet Technique , WebGIS Technique can issue geographic information. People can search and process geographic information with the help of WebGIS Technique. In this method, there have been feasible technical bases to implement opening and sharing geographic information.At present, some WebGIS softwares emphasize their universality, do few works on a given domain. When you construct a WebGIS application in a given domain, this will cost more high and make against the integration of the existent system. This paper selects Flood Control System domain for studying. First, this paper analyses characteristics of the application in this domain. And then this paper discusses some popular techniques of Web- GIS such as the spatial data org-anizing> distributed components and the structure of an application, and puts forward a WebGIS model.At last, this paper gives an example of this WebGIS model.
