WebGIS技术在气象网格产品精细化服务中的应用

Application of WebGIS Technology in Refined Service of Meteorological Grid Products

数值模式已经成为天气预报业务发展的主要方向,数值模式计算产生各种气象网格产品。气象网格产品具有数据量大、更新频次快、专业性强等特点,需要借助专业工具软件进行处理,不能很好满足企业和社会用户使用的需求,应用范围受到极大的限制。面对气象网格产品专业化与气象数据应用需求简单化之间的矛盾,文章提出针对气象网格产品,尤其是实况网格产品和预报网格产品,采用互联网服务手段,通过对网格数据离散化处理的方法,空间化管理的方式,将WebGIS技术应用到气象网格产品服务中。用户在客户端只需要进行简单文字检索或者GIS图形检索,系统便可以实现对气象网格产品中的有效数据进行精细化抽取,最终实现服务精细。文中提出的数据处理方法,对不同行业间气象网格产品的应用起到指导作用。

Numerical model has become the main direction of the development of weather forecasting.The numerical model calculation produces a variety of meteorological grid products.Meteorological grid products have the characteristics of a large amount of data,fast update frequency and strong professionalism.They need to be processed with the help of professional tool software,which can not meet the needs of enterprises and social users,and the application scope is greatly limited.Facing the contradiction between the specialization of meteorological grid products and the simplification of meteorological data application requirements,this paper proposes to apply WebGIS technology to meteorological grid products and services by means of Internet service,discrete processing of grid data and spatial management.Users only need to carry out simple text retrieval or GIS graphics retrieval on the client,and the system can realize the fine extraction of effective data in meteorological grid products and finally realize the fine service.This data processing method proposed in this paper plays a guiding role in applying meteorological grid products in different industries.
