摘要
目前,台风信息常以图形和文字的形式在Internet上发布,以这种形式发布信息存在与客户进行交互的功能不足,图形不能根据用户的请求实时生成,且很少有查询分析功能等缺陷,针对这一问题.本文提出了以WebGIS的形式发布台风信息,这样即能利用Internet的信息传播功能,又能利用GIS强大的查询分析功能,实现动态的、交互性强的又具有查询分析功能的信息发布。最后,本文在综合比较ArcIMS胖客户端和瘦客户端的特点,考虑负载平衡的前提下,选择ArcIMS的胖客户端模式设计和建立了台风信息发布系统。
At present, the typhoon information is always proclaimed by the way of graphics and literalness on the Internet. There are some disadvantages for this way, such as the shortage of interaction with the client, and lack of query and analysis function. To solve these problems, this paper puts forward the way of proclaiming typhoon information by WebGIS. It can make use of the function of Internet, GIS and proclaim information with the function of query and analysis. At last, This paper compares the characteristics of fat client with thin client's, and selects the fat client pattern of ArcIMS to design and develop the typhoon information proclamation system based on the consideration of the load balancing.
