基于开源RIA WebGIS的气象信息平台的设计与实现

摘要

The open source software and the technology of FLEX are described first. A solution of RIA WebGIS system is proposed. The framework structure and implementation mechanisms of this system are elaborated. Then a real-time display platform of meteorological information of automatic weather stations in Jiangxi province is developed based on the RIA WebGIS framework. The front part of the system is developed using Flex and OpenScales; the map service is based on GeoServer; PostgreSQL/Post-GIS is used for the spatial database. In this system, inquire, real-time display of the meteorological elements, and the general GIS functions are achieved.%在介绍开源软件和Flex技术的基础上,提出基于开源平台的RIA WebGIS系统解决方案,并详细阐述该系统框架结构和实现机制.基于该系统架构开发江西省自动气象观测站气象信息实时显示平台,系统前台采用Flex和Open-Scales,地图服务采用GeoServer,空间数据库采用PostgreSQL/PostGIS.系统实现了气象要素的查询、实时显示及常规GIS功能.
