流域“一张图”的制作是目前数字流域建设的热门话题，也是数字黄河建设中亟待研究的问题。以国家地理信息公共服务平台“天地图”为地理底图，叠加数字黄河信息资源，实现天地图和ARCGIS的地图服务聚合，解决黄河流域业务系统中的地图问题。黄河流域“一张图”的数据制作，为业务系统提供了一套便于统一使用、维护的多尺度地理空间数据集，为流域“一张图”的研究奠定了重要的基础。“,”The production of “a map” is a hot topic in the current construction of digital river basin,and it is also a problem needed to be studied in the construction of digitalYellow River. Withthe National Geographic Informa?tion Public Service Platform “map world” as geographic map,this paper stacked Digital Yellow River information resources to achieve the service aggregation of map world and ArcGIS map and solve the map problem in the busi?ness system of the Yellow River basin. The data production of “a map” in the Yellow River basin provides a set of multi scale geographic and spatial data set which is easy to be used and maintained in uniform,providing an important foundation for the study of“a map”in the basin.
