摘要
通过引入异步调用机制和缓存技术,提出了一种实时Web GIS优化模型,解决当前Web GIS中用户体验与空间分析能力之间的矛盾。文中详细描述了该优化模型的组成结构和工作原理,对异步调用机制和缓存技术的应用进行了讨论,并给出了性能测试和分析,验证了该实时Web GIS模型的可行性。
Through introducing asynchronous invocation mechanism and cache technology, this paper proposed a real-time Web GIS optimization model,resolving the contradiction between user experience and spatial analysis ability of the current Web GIS.This paper described the structure and principle of the model in detail, and discussed asynchronous invocation mechanism and cache technology applications, and had given the performance-test and analysis, it validated the feasibility of this real-time Web GIS model.
