中国从“十一五”末实施高分辨率对地观测系统重大专项，全面建设具备高空间分辨率、高时间分辨率、高光谱分辨率和高精度观测能力的自主、先进的对地观测体系，加强和完善相关基础设施，构建稳定的运行系统，并积极满足中国资源环境、农业、防灾减灾等方面的重大战略需求，着力强化各行业和区域应用能力，促进高分辨率对地观测数据广泛应用，推动中国空间信息产业快速发展，为中国从航天大国迈向航天强国，有效适应经济发展新常态促进信息消费、扩大内需提供有力支撑。

China High-resolution Earth Observation System (referred to short as CHEOS) was carried out at the end of "11th Five-Year Plan" of China, and has been comprehensive constructing independent and advanced earth observation system with the abilities of high spatial resolution, high temporal resolution, high spectral resolution and high precision, while strengthening and improving relevant infrastructure construction and forming stable operation system. CHEOS is actively meeting strategic demands for resources, environment, agriculture, disaster prevention and reduction, and so on of China, and focusing on strengthening application abilities of administrations and provinces of China, while promoting CHEOS data widely used and China's space information industry rapid developing. CHEOS will also support China to develop into space power country from space big country at present, and promote information consumption to expand domestic demands to effectively adapt to the new normal of China's economic.
