摘　　要：针对实时Web GIS应用对数据时效性要求高的特点,介绍了Web Socket的原理、特点及其相对传统方法的优势,并将Web Socket技术引入到实时Web GIS系统中,设计了一种基于Web Socket的实时Web GIS体系架构,在保证常规查询分析业务需求的同时又可以较好地满足实时Web GIS的时效性要求,提高了实时Web GIS系统的性能,为该类应用提供了有效的解决方案。For the requirement for data instantaneity in real-time WebGIS application, this paper introduces the principle and time WebGIS character of WebSocket and its advantages against traditional methods, then introduces WebSoket application and designs a WebSocket-based system architecture for real-time WebGIS which not antees conventional query and analysis requirement but also fill the instantaneity requirement and promotes the performance. This WebSocket-based system architecture also provides effective solution for other application into real- only guar- system ＇ s this type.
