基于WEBGIS的农业气象信息共享与发布技术应用研究

STUDY ON THE AGROMETEOROLOGICAL INFORMATION SHARE AND DELIVERY TECHNOLOGY BASED ON WEBGIS

依托全国气象部门观测台站通信网络 ,开展了基于WebGIS技术的农业气象信息共享与发布技术研究。根据气象行业标准和网络数据标准 ,对农业气象信息进行标准化处理 ,选用SQLServer 2 0 0 0建立了WebGIS应用系统所需的网络共享数据库 ,利用IIS、ArcIMS(InternetMapServer)构建农业气象信息服务WebGIS平台。采用JavaScript、ArcXML和ActiveX编程方式 ,结合ArcGIS和ArcIMSManager地理信息软件和管理工具 ,开发服务端的相关应用软件。在客户端实现了从属性到空间和空间到属性的农业气象信息双向查询以及农业气象信息专题地图分析功能 ,为用户提供详细、丰富。

Relying on the communication network of observation stations in the meteorology department all over China, the research on agrometeorological information share and release technology based on WebGIS is developed. The agrometeorological information is standardized basing on the standards of meteorology industry and network data, then the network share database required by WebGIS application system is established using SQL Server 2000, and the agrometeorological information service WebGIS platform is set up using IIS and ArcIMS(Internet Map Server).The application software about developing server applying Java Script、ArcXML and ActiveX which are combined with the geography information software of ArcGIS and management tool of ArcIMS Manager. The two-way search function from attribute to space and from space to attribute of agrometeorological information as well as thematic map analysis function of agrometeorological information are realized on client which can supply detailed、abundant and high quality agrometeorological information services for users.
