基于开源WebGIS的上海城市灾害信息系统

摘要

Design a system development program based on open source WebGIS which is high-efficiency and low-cost.Develop shanghai urban disaster information system as an example.The core of system which uses PostgreSQL as database is MapServer.The functions of system includes Web information publish, store and manage spatial data, provide map server, appease subsequent access by Multi-user, thematic mapping, query and statistics, spatial analysis and modeling, decision support, mapping output and so on.%利用开源WebGIS架构，设计了高效率、低成本的系统建设方案，并以上海市为例，构建了上海城市灾害信息系统。系统以MapServer为核心，使用PostgreSQL作为后台数据库，具备Web信息发布、空间数据的存储与管理等基本功能，提供了地图服务，可以满足多用户并发访问，并能实现专题地图、查询统计、空间分析与建模、决策支持、制图输出等多种功能。
