Abstract: China's FY satellite data have been applied in agricultural remote sensing for a long time. With the improvement of satellite technology, satellite data processing and distribution capabilities, the agricultural application of FY satellite data has been rapidly developed after the launch of the second generation of polar orbiting satellite. Chinese researchers have carried out a great deal of research work on crop growth monitoring, crop classification, crop planted area statistics and yield estimation, agricultural meteorological disaster monitoring, grassland ecological monitoring as well as the data processing, and achieved a lots. In near future, the tremendous potential of FY satellite data should be brought into the reality. The latest cloud computing of data processing and Internet-based information service technology will be used to provide timely, eきcient and accurate global crop production information for global agricultural monitoring in order to support the national food security strategy and the sustainable development goals of the United Nations.
