基于ArcIMS的农业气象信息发布系统

Agrometeorological information publication system based on ArcIMS

农业气象信息的可视化查询分析与统计是气象业务部门急需解决的问题,研究依托自动气象站网观测数据采集平台和通信网络,借助ArcIMS软件,开发了基于WebGIS的天津市农业气象信息发布系统(以下简称发布系统)。根据ArcIMS的体系结构特点,系统设计了数据层、应用层、浏览层的三层体系结构;针对自动站数据和温室数据的不同特点,设计了空间数据的文件组织方式和非空间数据的数据结构;以数据入库、配置地图文件,发布地图服务、二次开发定制等为流程,实现了系统功能。应用本研究的模式进行基于ArcIMS的系统开发,大大降低了系统开发成本、缩短了开发时间、方便了系统部署。将自动站数据和温室数据以WebGIS的形式发布,便于数据的直观显示,也使数据的查询分析更具交互性。系统在天津市气候中心的应用结果表明:界面设计简洁、操作简单、功能较强,很好的满足了气象部门日常信息管理及发布的要求,为农业生产提供了支持。

It is an urgent problem for the meteorological service department to visually query and analyze the agrometeorological information.Depending on the data collection platform by the auto-meteorological department net and the communication network,Agrometeorological Information Delivery System in Tianjin(AMIDS)was developed with the aid of the ArcIMS software.According to the characteristics of ArcIMS architecture,the three-layer architecture of AMIDS with data layer,application layer and browser layer was designed.In view of the different data attributes of auto meteorological station and greenhouse,the file organization method of spatial data and data structure of non-spatial data was designed.The functions of AMIDS were carried out by the process of data storage,map datum configuration, map service release and the second development custom and so on.The application of this research mode to system development based on ArcIMS,reduces cost and development time,and facilitates the system deployment.Releasing the data of auto station and greenhouse with WebGIS is convenient for visual display of data,making the query and analysis of data more interactive.The results of application in Tianjin Climate Center show that AMIDS with compact interface, simple operation and strong function meets the requirement of information management and delivery in the department of weather service and provides the support of agricultural production.
