Design And Implementation Of Drainage Information Publication Based On WebGIS

At present, with the high-speed development of city construction, the drainage pipe network system has become more and more complicated and huge. However the traditional artificial management has very big limitation, it cannot satisfy the demand of modern management of the city pipeline. Under this background, there is an utmost urgent demand for the establishment of city drainage management information system. Along with the popularization of Internet and the fast development of Web technology, the traditional single-machine mode GIS system cann't accommodate the user demand in the era of information. It is an important trend of GIS developing that GIS is based on Internet. Under this background, this paper presents the thought of establishing the Drainage Information Publication System based on WebGIS.Enclosing this theme,systematical research is carried out. First, the system construction and implementation technology and other related knowledge of WebGIS are studied,by analyzing and comparing some main platforms of WebGIS at home and abroad proposes resolution plan of issuing drainage pipe network information on web; Then proposes the overall designing of the system according to the characteristics of the Drainage Information System and practical requirements;Analyzes and proposes the management of the database of this system,the reasonable structure of the database and the method to combine the spatial data and attributive data based on the system functions ; at last ,based on above idea and method this system uses ArcIMS as map server,and ASP technology is applied to implement issuing drainage pipe network information on web.
