Most data are 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. While these data meet the quality standards and have the same geometric precision as data acquired on and after April 11, 2013, the geographic extents of each scene may differ. These data are also visible and can be downloaded from EarthExplorer or GloVis. ![]() Nearly 10,000 scenes were acquired by OLI/TIRS after launch (February 11, 2013) through April 10, 2013, when the satellite achieved operational orbit (WRS-2). Landsat 8 data products are consistent with all Landsat standard Level-1 data products, using the specifications described on the Landsat Processing Details page. I also worked closely with Formosa Interactive who provided complete audio services for the game from conceptualisation of SFX all the way through to final mix. ![]() Data rate: 384 Mbps on X-band frequency 260.92 Mbps on S-band frequency.Direct Downlink with Solid State Recorders (SSR).Weight: 2,071 kg (4,566 lbs) fully loaded with fuel (without instruments).Power provided by a single 9 x 0.4 meter solar array and one 125 Ampere-Hour (AHr), Nickel-Hydrogen (NiH2) battery.Products are scaled to 55,000 grey levels, and can be rescaled to the Top of Atmosphere (TOA) reflectance and/or radiance using radiometric rescaling coefficients provided in the product metadata file (MTL file). The 12-bit data are scaled to 16-bit integers and delivered in the Level-1 data products. Improved signal to noise performance enables improved characterization of land cover state and condition. OLI captures data with improved radiometric precision over a 12-bit dynamic range, which improves overall signal to noise ratio. This translates into 4096 potential grey levels, compared with only 256 grey levels in Landsat 1-7 8-bit instruments. The Landsat Archive Dashboard provides interactive map views of Landsat Collection. Band 5 Near-Infrared (0.85 - 0.88 µm) 30 m February 11 will mark the 5th anniversary of the launch of Landsat 8.Nine spectral bands, including a pan band:.The Thermal Infrared Sensor is built by NASA Goddard Space Flight Center. The Operational Land Imager sensor is built by Ball Aerospace & Technologies Corporation. Acquires 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.Has a 16-day repeat cycle with an equatorial crossing time of 10:00 a.m.Completes one Earth orbit every 99 minutes Interactive map ('Google Map style') of Ori and the Will of the Wisps in web browser.Achieved an altitude of 705 km (438 mi).Orbits the Earth in a sun-synchronous, near-polar orbit (98.2 degrees inclination).
