| 摘 要： | 网络技术的发展为实时动态地显示时空过程信息和在线分析提供了可能,也为气象海洋等灾害性过程的预警和防灾决策支持提供了可能;另一方面,随着网络的普及化,公众对GIS时空分析模型的网络实时集成和可视化表达提出了迫切需求。本文在分析网络GIS最新发展趋势的基础上,针对时空过程的动态特性,探讨了时空过程网络实时动态查询、分析和可视化的技术方法,并以台风过程为代表,设计了适合网络环境的台风过程数据的有效组织形式和直观的表达方式,构建了一个台风过程网络系统原型,具备了时空过程查询、可视化、简单的空间分析等功能,实现了台风过境的时空影响网络在线分析。系统基于ArcGIS Server在.NET环境下实现。实践证明本文提出的时空过程网络动态技术,可快捷地实现时空过程信息的网络发布、过程的在线影响分析及其时空动态可视化,可为台风、海啸等灾害性过程的信息提供和灾害评价等提供空间技术支持。

| 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. |
