How Long Does It Take To Create Landsat Collection 2 Level 2 Products Landsat 7 9 collection 2 level 1 scenes are available for download within 4 6 hours after acquisition. for landsat 7 collection 2 level 1 scenes, the timeframe from real time to tier 1 or tier 2 takes approximately 24 26 days to allow for application of the refined bumper mode parameters to the real time scene. Landsat 8 9 collection 2 level 1 scenes are available for download within 4 6 hours after acquisition. for landsat 8 collection 2 level 1 scenes it takes approximately 3 10 days to process to a tier 1 or tier 2 product while refined thermal infrared sensor (tirs) instrument line of sight model parameters are applied to the real time scene.
How Long Does It Take To Create Landsat Collection 2 Level 2 Products Collection 2 contains landsat level 1 data for all sensors since 1972. global level 2 surface reflectance and surface temperature scene based products are available for landsat data from 1982 to present. landsat u.s. analysis ready data (ard) tiled products are available for the conterminous u.s. from 1982 present. The usgs global visualization viewer (glovis) is an online search and download tool for select remote sensing data sets, including landsat collection 2 level 1 scenes. with easy to use navigation tools, users can narrow their search down by selecting targeted data sets, panning to a geographic location, defining parameters, and applying metadata filters, such as acquisition date or cloud cover. Source: usgs landsat headlines the usgs is currently finalizing the landsat collection 2 product definition structure, production timeline and public availability. however, for the landsat user community to have sufficient time to augment their current landsat collection based data processing flow, the usgs has released a high level summary of the landsat collection 2 product, as well as. Current collection 1–based products, such as landsat 8 and landsat 7 level 1, u.s. landsat analysis ready data, and level 3 science products, will continue to be generated and remain available for at least one year after collection 2 is publicly released.
