Design and Implementation of WebGIS for State-Owned Assets Management Based on MapXtreme and .NET

WebGIS emerged because of the rapid development of the computer technology, geographic information system (GIS) and internet. It is one of the most important aspects in GIS studying at present. This paper started from the current research situation of WebGIS and talked over the architecture and characteristics of WebGIS, the choke points in WebGIS development currently was also discussed, such as the common interface technology, the methods of sharing and interoperating the spatial information and the rate of transmission. Aiming to all these problems, the author combined the predecessors' study and the research experience of his own in this field, and then he put forward a new method in developing WebGIS, that was choosing the .NET as the development platform, combining the MapXtreme which is the MapInfo's component and ASP.NET technology, in order to overcome the defects of the rate of transmission and the server burden. The author checked up this method through building up the information system of management to state-owned assets for southwest university of science and technology, practice shown that it could achieve a satisfactory result. So, I think this method will provide a new direction for WebGIS studying.
