【摘要】 应用WebGIS技术,开展了网络化农业气象信息服务技术研究。利用SQL Server2000建立了WebGIS应用系统所需的全国农业气象网络共享数据库。利用ArcIMS(Internet Map Server)4.0平台构建农业气象信息服务WebGIS服务器,实现了客户端的农业气象空间和属性数据交互查询和专题图分析功能。探讨了针对Internet网上发布需要的产量动态预报解决方案。基于WebGIS的农业气象信息共享技术将使农业气象信息直接、迅速、便捷、有效地传输到农业生产第一线,具有广泛的应用前景。更多还原

【Abstract】 Aimed at the rapid development of information techniques and large social and market requirement for agrometeo-rological information, the agrometeorological information service techniques based on WebGIS are carried out. Nationwide network agrometeorological database of required for WebGIS is established by SQL Servre2000. The WebGIS server for agrometeorological information service is set up on ArcIMS (Internet Map Server)4.0 platform. The strong function of query for space and feature data at client-side and function of thematic map analysis are developed. The solution to dynamic predicting crop yield meeting the demand for Internet users is also discussed. The sharing techniques of agrometeorological information based on WebGIS will make it possible to transport agrometeorological information to farmers and decision-makers quickly and directly. It is of broad application value.更多还原
