Research and application of the WebGIS based on ArcIMS and Ajax

The advantages of using the Ajax technology in WebGIS, such as updating pages without refreshing, balancing the server and client load, updating the map dynamically, which improving user´s experience. ArcIMS because of its cross platform supports multiple development languages, and good scalability has become the most popular WebGIS platform. In this paper, we analyze Ajax technology and ArcIMS, and bring forward a developing approach for WebGIS based on Ajax and ArcIMS, moreover the method has been applied to the development of internet bar control and supervisory system. Experiment illustrates that the program implements the browser and asynchronous interaction between the WebGIS servers, so that the best performance of the entire state of WebGIS.
