摘　　要：结合中国气象局应急平台气象服务产品生成业务的需要,详细讨论基于COM的GIS二次开发技术和Arc GIS Model Builder建模技术,以类似工作流的方式构建模型,通过气象自动出图系统(Meteo Carto Builder)自动调用模型对各类气象数据进行处理加工,形成栅格数据后存储到空间数据库引擎Arc SDE中,同时实现Arc SDE中栅格数据的实时更新。达到气象产品数据自动化更新,管理方便,具有很强的实时性,以满足第三系统数据实时更新的需要,在气象服务产品制作中表现出较强的应用能力。According to the business requirement of meteorology service products in China Meteorological Administration emergency platform, dis- cusses the secondary development of GIS based on COM technology and ArcGIS Model Builder modeling technology, builds models simi- lar to work flow diagrams. Then MeteoCartoBuilder is used to call models to process multiform meteorological data to form raster data and store the raster data into the Spatial Database Engine （ArcSDE）. At the same time, updates the raster data in ArcSDE in real time, thus the data of meteorological product can be updated automatically, managed conveniently and have a strong real-time to meet the needs of real-time update of data in another system.
