With the support of the national science and technology programs,China has been gradually accumulateda series of key technologies and core achievements in the field of earth observation since 2000. Taking this as an important lead, it has formed a series of operational remote-sensing satellites for meteorology, marine and land resources, and a series of multi-category remote-sensing scientific experiment satellites. Relatively comprehensive data acquisition systems for satellite andflexible and diverseaerial remote-sensing datawere created. At the same time, the systemsfor data acquisition, processing, product services and applications oriented to different needs weredeveloped to meet daily and emergency needs of major industries. In particular, the establishment of the earth observation and navigation field in the National High Technology Research and Development Program (namely 863 Program) and the implementation of the National Major Science and Technology Project “China High-Resolution Earth Observation System(CHEOS)” have systematically strengthened China’s overall earth observation technology and capability. Through multi-lateral and bilateral internationalcooperation, China started to play a leading role in the global earth observation process, and has developed and consolidated important international cooperation channels such as Sino-EU, Sino-US. With the continuous development of talent teams, the cultivation environment for industry-university-research cooperation promoting the commercialization of remote-sensing scientific and technological achievements has being constantly improved, and a number of leading enterprises have emerged. Diversified commercial remote-sensing satellites have begun to take shape, and various types of remote-sensing products were booming, and a number of typical enterprises have emerged. In the future, the space-air-ground integrated observation capability, quantitative information acquisition technology, and intelligent observation will be further developed. The remote-sensing big data management technology and the sharing service mechanism will also have new breakthroughs.
