The Institute of Remote Sensing and Digital Earth (RADI), Chinese Academy of Sciences (CAS), was established on 8 November 2012, through the merging of two CAS institutes: the Institute of Remote Sensing Applications (IRSA) and the Center for Earth Observation and Digital Earth (CEODE).

As a scientific research institute, RADI was established as a major initiative of CAS “Innovation 2020” Program and “one positioning, three breakthroughs, five important fostering directions” project ( the “one, three, five” project for short ). The consolidation will pool the advantages of both CAS institutes in the fields of remote sensing and Earth observation to promote the development of cutting-edge scientific research, and to meet national strategic demands.

The strategic objectives of RADI are to explore leading technologies in Earth observation and the mechanisms for acquiring and distributing remote sensing information. RADI will focus on the construction and operation of major Earth observation infrastructure and the air-space-ground integrated Earth observation technology system. RADI will enhance its capacity for providing resource-environment spatial information at regional and global levels by establishing a digital Earth scientific platform, therefore building itself into a comprehensive, world-class research institute.
