A partnership has been established between European Space Agency (ESA) and the United States Geological Survey (USGS) to allow for USGS storage and redistribution of data acquired by the multispectral instrument (MSI) on ESA’s Sentinel-2A satellite that was launched in June 2015. The MSI collects imagery over the Earth’s land surfaces, large islands, and inland and coastal waters with potential revisit every ten days. The MSI sensor acquires 13 spectral bands that are highly complementary to data acquired by the USGS Landsat 8 Operational Land Imager (OLI) and Landsat 7 Enhanced Thematic Mapper Plus (ETM+).
