Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted. For more information, please see www.doi.gov/shutdown
December 13, 2018- Landsat Level-3 Science Product Samples Available
The science product samples are delivered in U.S. Landsat Analysis Ready Data (ARD) tile format defined in the Albers Equal Area Conic map projection referenced to the WGS84 datum. These products represent specific geophysical and biophysical properties of the land surface. Development of these terrestrial variables uses measurements collected from the Landsat Thematic Mapper (TM), Enhanced Thematic Mapper Plus (ETM+), and Operational Land Imager (OLI)/Thermal Infrared Sensor (TIRS) instruments from 1982 to present. This 36+ year record at 30-meter spatial resolution allows for the discrimination and study of natural and human-induced changes to the Earth’s land surface.
