Technical Information (Including calibration and definitive ephermeris files).EE provides an enhanced user interface using state-of-the-art technologies for searching, viewing, and downloading data. Landsat Spectral Characteristics Viewer EarthExplorer (EE) provides online search, browse display, metadata export, and data download for earth science data from the archives of the U.S.USGS Landsat - Earth Observations Satellite Fact Sheet.The Landsat Collections page contains additional information about changes applied to Landsat Level-1 data products for Collection 1. Users interested in Tier 2 scenes can evaluate the L1TP RMSE and other properties to determine suitability for use in their applications and studies. Tier 2 (T2) – Contains L1TP scenes not meeting Tier 1 criteria and all Systematic Terrain (L1GT) and Systematic (L1GS) scenes.The georegistration is consistent and within prescribed tolerances. Tier 1 (T1) – Contains the highest quality Level-1 Precision Terrain (L1TP) data considered suitable for time-series analysis.These data have well-characterized radiometric quality and are cross-calibrated among the different Landsat sensors. Collection 1 Categories The purpose of Collection categories is to support rapid and easy identification of suitable scenes for time-series pixel level analysis.ĭuring Collection 1 reprocessing, all Landsat 1-5 MSS scenes in the USGS archive are assigned to a specific “Tier”. All scenes in the Landsat archive are assigned to a Collection category. Landsat Tiers are the inventory structure for Landsat Collection 1 Level-1 data products and are based on data quality and level of processing. These datasets can be found on EarthExplorer. Specific Level 1T scenes are available for most of the globe under the Global Land Surveys (GLS) collections of 1975, 1990, 2000, 2005, and 2010. (See Landsat Processing Details for details on correction levels.) In these cases, the best level of correction is applied. While most Landsat scenes are processed with the Standard Terrain Correction (Level 1T), some scenes do not have the ground-control or elevation data necessary to perform these corrections. Landsat MSS scenes take 3 days to 1 week to process. Immediate for scenes already processed and ready for download.
