摘　　要：本文以我国自主高分辨率遥感立体测图卫星为主要数据源,利用高精度卫星影像无地面控制几何定位技术和智能采编技术,研制了全球陆域范围统一框架下的多尺度、多类型的基础地理信息产品,以发挥测绘地理信息在全球治理和可持续发展方面的重要作用,为"一带一路"倡议,国家经济社会发展,全球战略实施,智慧社会建设提供科技支撑。Based on the high-resolution remote sensing stereo mapping satellite of China as the main data source,the multi-scale and multi-type global geographic information products under a unified framework are developed by using high-precision satellite images without ground control geometric positioning technology and intelligent acquisition and compilation technology.It will play an important role in global governance and sustainable development,and provide scientific and technological support for the building of"the Belt and Road",national economic and social development,global strategy implementation and the building of a smart society.
