基于客户端模式的WebGIS实现技术

WebGIS Realization Technology Based on Client End Mode

基于客户端模式的WebGIS具有访问范围更广泛、平台独立、系统成本低、操作简单、计算负载平衡高效等优点。可通过客户端请求地图图像的方式、客户端请求图形元素的方式及客户端请求空间数据的方式实现。未来的WebGIS将在GIS与GPS和RS的集成、三维GIS、时态GIS、虚拟GIS技术的基础上获得发展。

The WebGIS based on client end mode has merits such as wide interview area, independent platform, low cost, easy operation, balanceable and effective calculation load. It can be realized through methods such as client end asking for the map image, the client end asking for image elements and the client end asking for the space data. The future WebGIS will develop based on the integration of GIS, GPS and RS, three-dimension GIS, tense GIS and virtual GIS.
