Abstract

To manage drainage-networksystem of Hochiminh city, the city’s Urban Drainage Company has been developinga desktop GIS based on ArcGIS software, and ArcEngine library of ESRI. In thissystem, drainage database is organized into Geodatabase model and is stored ina server placed at the company headquarter. In order to allow staffes from thecompany’s satellite offices get access to the server’s database, it isnecessary to build a WebGIS system. With this webGIS, the staff with permissioncan access to drainage database from everywhere through the Internet by usingjust a normal web browser. To reduce investment cost, a WebGIS system has beendeveloped based on open source products Geoserver, and OpenLayerscombined usingprogramming language Javascript and Jquery library. The system allows toimplement basic functionssuch as i) display drainage-network data on base mapof Open Street Map ii) retrieve attributes by direct interact with drainagefeatures on map iii) search for features based on their attributes iv) searchfor features in spatial relationship with other features, … The system has beentested and proved to work effectively in exploiting the drainage-networkdatabase through the intern
