土壤湿度同化数据综合分析处理系统的研制与开发

Research and Development of the Comprehensive Analysis and Processing System on Soil Moisture Assimilation Data

陆面数据同化系统的输入和输出数据以其格式多样性、海量性为主要特征。以GIS二次开发组件ArcGIS Engine,ArcSDE空间数据库引擎和SQL Server 2005数据库管理工具,利用C#、IDL编程语言,构建土壤湿度同化数据空间数据库,并将气象数据具有时间域、空间域和属性域等多维属性与GIS数据模型相结合,研制开发综合分析处理系统,实现土壤湿度同化输入参数与输出数据的空间分析与管理。系统能够满足陆面同化系统对数据的处理与分析需求,为土壤湿度同化产品的业务应用提供强大的支撑。

The input and output data of Soil Moisture Assimilation system was characterized by diversity,massiveness in format.By using the ArcGIS Engine as GIS application the development component,the ArcSDE as spatial database engine and SQL Server2005 as database management tools,the soil moisture assimilation data spatial database has been build.Comprehensive analysis and processing system the soil moisture assimilation data provides a new way for soil moisture assimilation data spatial analysis and statistics.The system can satisfy the demands of data processing and analysis for the Land Data Assimilation system and provide a powerful support to business applications of the soil moisture assimilation products.
