Description
Abstract:The Landsat 8 OLI/TIRS Pre-WRS-2 data set contains nearly 10,000 scenes acquired by the Operational Land Imager (OLI) and/or Thermal Infrared Sensor (TIRS) sensors after launch (February 11, 2013) through April 10, 2013, when the satellite achieved operational orbit (WRS-2). The earliest images are TIRS data only. While these data meet the quality standards and have the same geometric precision as data acquired on April 11, 2013 and beyond, the geographic extents of each scene will differ. Most data will be processed to an L1T (as other standard products), and the pixel size will be 30 meters. There may be some differences in the early TIRS images due to telescope temperature changes, although they should be within +/- 1 percent. The data acquired during the Landsat 7/Landsat 8 underfly on March 29 - 30, 2013 are also available.
