Abstract

The rapid development of web technology provided possibility for supporting spatio-temporal process information and analyzing timely on line, and as a powerful tool it can also provide support for forecasting meteorological ocean disaster process. And on the other hand, with the popularization of WebGIS technology, the web real time integration and visual expression of Geographic Information System (GIS) spatio-temporal analysis model are also required urgently by people. It is necessary to build a new kind of model or method of GIS according to the special characteristics. Based on the analysis of the latest WebGIS technology, this paper discussed the method of querying, analyzing and visualizing the spatio-temporal process dynamically on line. And taking the typhoon process as an example, it organized and expressed typhoon process data effectively in web environment, and also constructed a prototype of typhoon process web application system which can realize spatio-temporal process’s dynamical querying, visualizing, simple spatial analysis, etc. Based on that, it realized a spatio-temporal influence analysis of typhoon motion. The system was accomplished based on ArcGIS Server in dot net environment. Practice that GIS spatio-temporal process web dynamical method introduced by this paper can publish spatio-temporal process information, analyze influence on the web and also can visualize space-time dynamically. Furthermore it can forecast and estimate disaster process such as typhoon and seaquake, and provide spatial technology support for making decisions.
