The Design And Implementation Of The Webgis Of The Water Conwervancy Information System For The Township

Geographical information system own to get deeply to social all department of life and production gradually as one information technology. With the swift and violent development of Internet technology, WWW geographical information system(WEBGIS) based on WWW agreement emerges rapidly, becomes important developing direction of the geographical information system. WWW geographical information system(WEBGIS) is the GIS that bases on Internet platform, and adopts WWW agreement as its customer end application software.It realizes geographical information data stored distributedly and visited on other place making use of Internet technology, thus further develop and improve the geographical information system. Design and Realization of WEBGIS on Villages and Towns is designed basing on this kind of thought. This system can input, storage, see and manage all kinds of space data what feeds back the status quo, programming and vicissitude on villages and towns, just as landform, building and roads, and also the attribute data which expresses the space character.Firstly, the article indicates the background and significance, and the design thought.Secondly, this article describes the requirement analysis and the feasibility analysis by software engineering method. Thirdly, the article enumerates the systems’ environmental of development, and modular design for a specific presentation. Finally, putting forward the conclusion. It mostly describes the writer’s experience and prospect about this design.
