Abstract: This paper takes Shanghai Expo Park as an case, proposes the system logic framework and software design method of energy and environment monitoring WebGIS based on Linux. It anaylzes the key technologies including map server pooling, map cache management, dynamic map rendering and cross domain data access on Web etc., and gives the implementation method of the system modules. The study production has carried out the mission of monitoring and analysis on the energy and environment in Shanghai Expo Park successfully.

Key words: Linux operating system, energy and environment monitoring, WebGIS, map rendering

摘要： 以上海市世博园区为例，提出一种基于Linux的能源与环境监测网络地理信息系统(WebGIS)，给出系统的逻辑框架和软件设计方法。对地图服务对象池技术、地图缓存管理、跨域数据访问策略、动态地图渲染、客户端矢量要素绘制等关键技术进行分析，给出各系统模块的实现方法。应用结果证明，该系统能有效实现上海世博园区能源与环境的监测和可视化分析。
