Rrelated Technology For Digital Pipeline Network Geographic Information System Based On Flex And ArcGIS

WebGIS is a typical web-based GIS. Currently, the demand for application of WebGIS invarious area is growing sharply. With the development of network and GIS technology, theusers demand more in performance, interaction, the speed of response and the functionexperience based on the web-page of WebGIS.RIA (Rich Internet Applications, Rich Internetapplication) technology provides a new Web application solution, brings new developmentopportunities to WebGIS, to achieve a more intuitive and efficient application services. FlexRIA development is one of the mainstream technology currently. To solve the poorinteractivity,slow response, scalability is not strong and other shortcomings in the applicationof traditional WebGIS, the author did in-depth research in Flex technology, and presents anapproach based on ArcGIS Server for Flex the WebGIS design.Firstly, The paper analyzes the Flex technology and WebGIS research status and keytechnology. Then based on Xiangguosi gas pipeline WebGIS digital library project, theauthor analysized the figures of the characteristics of the gas pipeline management andbusiness process design and implementation the database of this system. By digitizing thepipeline geographic information system service layer design, the author studied Flex andArcGIS Server, Flex and Dot Net communication, to achieve a connected client andgeospatial data and business data. According to the demands of users, as well as the goals andthe principles of digital design pipeline WebGIS, the author designed and implemeted the B/S structure of the digital pipeline WebGIS. Lastly,the paper confirms that Flex technology isoperable and has a splendid applied foreground inimproving interactivity and expressivenessof WebGIS.
