The Chinese Land Satellite Remote Sensing Application Centre (LASAC) under the Ministry of Nature Resources has very generously shared with the International Society for Photogrammetry and Remote Sensing (ISPRS) sample data from China's Natural Resources Satellites for scientific research and education. The shared data can be freely used for non-commercial purposes by the whole society free of charge. This is the first time that ISPRS has been offered such a wide range of open-access satellite imagery for the scientific and academic community.
The sample data consists of sensor-corrected (SC) products from China’s Natural Resources Satellites, including ZY3, GF-1, 2m/8m Optical, GF-2, and 5m Optical, which provide stereo mapping, 2m-resolution optics, 1m-resolution optics, and hyperspectral imaging. The data comprises 175 scenes, with typical geomorphic features.
The sample data shall only be used for non-commercial purposes such as scientific research and education. Data application reports or questions are welcome. Please contact to Lyu Shanshan from LASAC at lvss@lasac.cn or 905872648@qq.com.
