    摘要:

    将气象数据分为离散数据、格网数据和要素数据,在此基础上,建立了气象数据库,包括气象资料信息数据库、社会资料信息库、基础地理数据库和气象空间数据库,并详细分析了气象数据的组织结构、表达和处理方法,最后提出了基于GIS的气象数据管理与表达的处理方法.

    Abstract:

    Due to its different acquisition methods,meteorological data has characteristics of various kinds,formats and numerous data amount.Besides observation data,radar data,satellite image,meteorological data includes derivativeouts products,such as numerical forecast,radar rainfall estimation,typhoon track prediction,etc.With its rapid development,GIS has played an important role in meteorological field,and the combination of GIS and meteorological application model is becoming more and more close.However,the diversification of the meteorological data's storage format,storage method and data display,as well as the widely involved field of meteorological service industry,cause difficulty in the widespread use of GIS in meteorological domain.In this study,meteorological data were divided into discrete data,grid data and element data.On this basis,a meteorological database,includes meteorological information,social information,fundamental geographic data and meteorological spatial information,were put forward,and the general structure,display and processing of meteorological data were described in detail.Finally,a GIS-based treatment scheme of data management and expression was proposed,which has been used in meteorological departments now and can meet meteorological service requirement.
