基于MapXTreme的WebGIS-T设计与实现

Design and Implementation of the WebGIS-T Based on MapXTreme

分析了用MapXTreme for java开发WebGIS体系的现状和优缺点,结合WebGIS-T系统中交通流量数据动态显示的特性,提出了Ajax+Servlet+MapXTreme Java的体系结构实现WebGIS-T系统方案,以充分利用Ajax良好的异步传输功能。以杭州市为例,在MapXTreme WebGIS操作界面上,通过实时交通流量数据的图形分析和显示,直观显示杭州市道路的交通拥堵状况。

The advantages and disadvantages of the developing technology on WebGIS by Mapxtreme for java were analyzed and compared. According to the characteristics of displaying traffic flow data dynamically in WebGIS-T, the method and architecture of Ajax joint Servlet and MapXtreme Java were proposed with the function of asynchronous transmission. In the operation interface of Mapxtreme WebGIS in Hangzhou, the urban traffic status can he displayed visually by displaying the real time traffic flow.
