【摘要】 Google Maps的Ajax客户端为WebGIS开发提供了新思路。该文从3方面讨论了Ajax在WebGIS中的应用。在原理方面,通过分析Ajax模型和Google Maps,阐述了Ajax方法与OGC规范相结合的客户端模式;在实现环节,以MapBuilder为例分析了Ajax客户端的实现模式及功能扩展方法;在应用方面,介绍了基于GeoServer和Map-Builder实现的淮河流域水环境信息网络查询原型系统实例。更多还原

【Abstract】 Much attention is abstracted by Google Maps’ Ajax Client.So this paper discussed why and how to integrate Ajax approach into WebGIS.Firstly,the client pattern based on Ajax approach and OGC specifications was discussed after analyzing Ajax Model and Google Maps.As a case study of design model and function extension of MapBuilder,an Ajax client application was discussed in detail.Finally,the authors briefly presented the prototype of Water Environment Information System of Huaihe River based on GeoServer and MapBuilder.更多还原
