【摘要】 针对动态生成和发布GIS图幅的WebGIS应用系统以及多用户并发访问问题 ,提出了一种基于负载平衡方法的解决方案。用户动态生成和发布GIS图幅过程需消耗大量的服务器系统资源 ,使服务器处于严重的瓶颈状态 ,设定一个专门的负载平衡服务器来管理多个GIS服务器。客户端在进行GIS请求时首先访问该服务器 ,负载平衡服务器检测每个GIS服务器是否是处于饱和状态 ,若有未饱和的GIS服务器则让请求客户端连接到此服务器上进行GIS图件服务 ,从而解决了多用户并发访问时的瓶颈问题。设计并实现了B/S模式的基于WebGIS的地质图幅生成与发布系统 ,取得了较好的应用效果更多还原

【Abstract】 A method that generate and public WebGIS map based on load balancing method was brought forward,aiming to WebGIS application system that generate and release GIS map dynamically and multi-client concurrency accessing.Because the application require to use abundance system resources of server,which make the server be in a choke point.There are have a balancing server that administrate multi GIS servers that provide GIS map server to client.Client must request balancing server before visit GIS server.Balancing server assign a unfilled GIS server to the request user offering GIS services.Thus it resolved above problem.Using this method,designed and developed “Geology map generate and release system based on WebGIS”,acquired preferable effect.更多还原
