基于开源GIS的生态质量气象评价系统

摘要

In order to meet the needs of the application of ecological quality meteorological evaluation technology, the authors designed a service system by using open - source GIS(MapWinGIS) technology in C# develop environment. This system has carried out the analysis and processing of climate data according to the needs of service process. By using MapWinGIS interfaces and class libraries, this platform has achieved the design and development of GIS function. And by self-developed writing class,this platform has the function of the processing of meteorological evaluation data including the MODIS remote sensing data and index calculation,finally obtaining the comprehensive evaluation index of ecological quality by using the GIS map. This system provides a standardized work flow for the ecological quality evaluation.%为了满足生态质量气象评价技术成果应用的需要,利用开源的地理信息系统(geographic information system, GIS)技术——MapWinGIS,在C#开发环境下,设计开发了广西生态质量气象评价业务系统.该系统从业务流程需要出发,实现了气候数据的分析处理,利用MapWinGIS的接口和类库实现了业务平台中GIS功能的设计与开发.通过自主开发编写的类,实现了包括MODIS遥感资料等气象评价数据的处理及指数计算,进而得到生态质量综合评价指标,最后利用GIS地图生成业务产品.该系统为生态质量气象评价业务工作提供了标准化的工作流程.
