基于AJAX技术的WebGIS研究和实现

Study on the WebGIS Based on AJAX Technology and Its Realization

GIS与Web服务的结合,为跨平台的地理信息共享和互操作提供了一种松散耦合、灵活的体系架构。而目前WEBGIS大多通过同步通讯方式完成,服务器负担重,网络带宽占用严重。本文提出了一种基于OpenGIS规范,运用AJAX技术异步传输机制实现WEBGIS的解决方案,提升了系统运行效率,改善了用户Web应用的体验。

The combination of GIS and Web service provides a flexible system construction for the eross-platform sharing of geography information and mutual operation. However, most of the present WEBGIS are finished in the way of synchronous communication. The servicer shoulders heavy burden and the occupation of IDSL is severe. This paper proposes a solution to the realization of WEBGIS basing on OpenGIS and asynchronous transmission with AJAX technology, which increases the operation efficiency of the system and improves the users＇ experience in Web application.
