The Research Of Network Based MapData Visualization Method And Its Applications

The Network based map data visualization is a fast developing technology, which widely used for efficiently decision making and information representation.Based on AJAX and WEBService ,WEB-GIS is one of most active sub-discipline in network based Map data visualization research area,which is also the new WEB-GIS most emerging technology. This technology can guarantee the accuracy, timeliness, the usability of map data. Consequently, the research of network based geographic data visualization method is significant and valuable either in theory or application areas.The article based on the trends of current network development, and integration of AJAX and the WEBService technology to examine and evaluate the WEB-GIS method, and find out that AJAX and WEBService technology which can work with low end client by a WEBpage system with the dynamic updating to represent the information or the data to users without any download.The paper analysis the electrical network information platform's demand and unifies the actual subject, by establishing an electrical network information platform of.And it has given the concrete design and the implementation plan to confirm this article.Using Oracle9i as the data storage the tool, the system uses JSP, JavaScript, XML, CSS, HTML to develop the electrical network geography information platform on. the environment foundations of system ofMicrosoft Windows 2003 Server,Microsoft in Excel 2003 .
