True-color image of lithium mining in Salar de Atacama, Chile. Salar de Atacama is the largest salt flat in Chile and the third largest salt flat in the world. Located in the Lithium Triangle, it is also the world's largest and purest active source of lithium. This image was acquired on January 8, 2023, by the Multi-Spectral Instrument (MSI) aboard the ESA (European Space Agency) Sentinel-2A and -2B satellites. Explore this image in Worldview.
The imagery available in NASA's Worldview are part of the Harmonized Landsat Sentinel-2 (HLS) project, which provides 30-meter resolution, true-color surface reflectance imagery from the Operational Land Imager (OLI) and OLI-2 instruments aboard the joint NASA/USGS Landsat 8 and Landsat 9 satellites and the MSI aboard ESA's Sentinel-2A and -2B satellites. The data from the two instruments aboard the four satellites are processed through a set of algorithms to make the imagery consistent and comparable across the instruments. This includes atmospheric correction, cloud and cloud-shadow masking, spatial co-registration and common gridding, illumination and view angle normalization, and spectral bandpass adjustment.
