Research and application outlook of land satellite remote sensing monitoring system

In recent years, new requirements have been put forward to land remote sensing monitoring generated from the natural resources conservation, the national land spatial planning, implementation and supervision, the ecological restoration and the studies of global change. Benefiting from the rapid developments of land satellites and the widely applications of advanced technologies such as artificial intelligence, the important foundation of the reconstruction of land satellite remote sensing monitoring system has been established. Based on the observation capability of domestic land satellites, this paper proposed the construction of the land satellite remote sensing monitoring system by making full use of such high and cutting-age technologies such as big data, artificial intelligence and cloud computing, while the technical flow of nation-wide operational application was also designed. Moreover, by breaking through a series of key technologies of remote sensing monitoring, the quarterly monitoring of all types of land use in China, high-frequency and accurate monitoring in key areas, and real-time monitoring of specific targets have been realized, which has been adopted in applications such as the law enforcement inspector of natural resources and surface water change monitoring.
