摘要
从现有的大部分WebGIS系统的研究情况来看,界面都比较简洁美观,功能都比较健全实用,缺陷就是响应速度慢,等待时间长。该文就是从用户响应速度这一角度分析了WebGIS系统设计与开发中的问题,详细剖析了WebGIS中决定用户响应速度的各种因素。其中系统开发方式是决定速度的首要因素,对数据的操作方式、自适应模式和服务器集群结构对速度的影响也很大。在开发过程中,根据系统开发的需要及具体情况来综合考虑这些因素,对用户响应速度将会有明显的提高。
In many WebGIS Systems, user interface is concise and beautiful, function is power and useful, but user responding speed is too slow and waiting time is too long. This paper presented some issues in designing and developing WebGIS System from the point of view of responding speed, analyzed all factors of determining consumer responding speed. First, GIS service design is the most important factor of determining speed. And the management of GIS data、Self-Adaptive system、cluster server machines are all working on the speed. So, if we integrate with all this factors according to the system, the responding speed will improve obviously.
