Nearly 10,000 scenes were 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). Landsat 8 aquires about 740 scenes a day on the Worldwide Reference System-2 (WRS-2) path/row system, with a swath overlap (or sidelap) varying from 7 percent at the equator to a maximum of approximately 85 percent at extreme latitudes. These data are also visible and can be downloaded from EarthExplorer or GloVis. O Programa Landsat foi iniciado em 1972. Most data will be processed to the highest level possible, however there may be some differences in the spatial resolution of the early TIRS images due to telescope temperature changes, but they should be within +/- 1 percent. The Thermal Infrared Sensor (TIRS) instrument is the thermal-band imager on the Landsat-8 platform. The data from Landsat spacecraft constitute the longest record of the Earth’s continental surfaces as seen from space. The data are useful to a number of applications including forestry, agriculture, geology, regional planning, and education.
