What is Landsat Collection Level2?
Landsat Collection 2 includes scene-based global Level-2 surface reflectance and surface temperature science products. Landsat 8 Operational Land Imager (OLI) surface reflectance products are generated using the Land Surface Reflectance Code (LaSRC) algorithm (Version 1.5. …
What is Landsat Collection 1 level1?
Landsat Collection 1 consists of Level-1 data products generated from Landsat 8 Operational Land Imager (OLI)/Thermal Infrared Sensor (TIRS), Landsat 7 Enhanced Thematic Mapper Plus (ETM+), Landsat 4-5 Thematic Mapper (TM)*, and Landsat 1-5 Multispectral Scanner (MSS) instruments.
What is Landsat collection Level 1?
What’s the difference between Landsat Collection 1 and 2?
In comparison, Landsat Collection 1 Level-2 products are only available via on-demand processing (Surface Reflectance, scene-based), or within Landsat Collection 1 U.S. Analysis Ready Data (ARD) (Surface Temperature, tile-based). The table below provides a brief overview of the differences between Collection 1 and Collection 2 Level-2 products.
Can you use Landsat MSS 1-5 in Level 2?
Landsat MSS 1-5 data cannot be processed into Level-2 products at this time. Landsat Collection 2 Level-2 products require Landsat Collection 2 Level-1 scenes that have been processed to Tier 1 or Tier 2, as well as additional auxiliary data.
How are Landsat Level 2 science products generated?
Landsat Level-2 science products are generated from Collection 2 Level-1 inputs that meet the <76 degrees Solar Zenith Angle constraint and include the required auxiliary data inputs to generate a scientifically viable product.
How is surface reflectance calculated in Landsat 2?
Surface reflectance is generated from Level-1 inputs that meet the <76 degrees Solar Zenith Angle constraint and include the required auxiliary data inputs to generate a scientifically viable product.
