True-color image of Sutter Buttes in the Central Valley of California. The Sutter Buttes are the circular configuration in the center of the image and stand in contrast to the surrounding agricultural fields. These are remnants of volcanic activity and have been dormant for over a million years. This image was acquired on April 24, 2023, by the Multi-Spectral Instrument (MSI) aboard the ESA (European Space Agency) Sentinel-2A and -2B satellites. Explore Sutter Buttes 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.
