基于XML／MobileSVG的WebGIS模型研究

The Research of Land Resources Information Service System Based on WebGIS

在分析了WebGIS的特征和XML／MobileSVG技术的优势后，采用（Browser／Server）多层模式技术，提出了一个前端采用SVG作为图像的显示格式，服务器端采用JSP＋Servlet技术动态生成SVG文件，能支持多种地理数据库的通用实时webGIS模型。实践证明无论在实时性、灵活性、可扩展性、可移植性都大大优于其他的实时信息发布模型。

After analyzing the specialty of Web GIS and the advantage of XML/SVG,It put forward a real time Web GIS system model based on B/S(Browser/Server)mode.SVG was the map display form of the client of this model,on the JSP+Servlet technique it dynamically builds SVG file,supports many geograph and realizes a universal real time Web GIS model.It is proved that both in real-time,flexibility,scalability,portability,it is greatly superior to other real-time information publishing model.
