I want to download the Level 0 product which should only contain the DN values, with no-processing. From where can I download the files. Please guide. Thanks
Hi , The Level 0 products of Landsat 1-9 are not publicly available for download. The Level 0 data refers to the raw, unprocessed instrument data from the Landsat satellites, which is not typically distributed to end-users.
The lowest level of Landsat data that is publicly available is the Level 1 data product. Level 1 data is the most fundamental level of Landsat data that has been processed to remove radiometric and geometric distortions, and is typically the level of data used for most applications.
You can download Landsat Level 1 data from the following sources:
USGS EarthExplorer (https://earthexplorer.usgs.gov/): This is the primary source for downloading Landsat data from the United States Geological Survey (USGS). You can search and download Level 1 data products for Landsat 1-9 missions.
USGS GloVis (https://glovis.usgs.gov/): Another data portal provided by the USGS for searching and downloading Landsat Level 1 data.
Amazon Web Services (AWS) Public Dataset (https://registry.opendata.aws/landsat-8/): AWS hosts a public dataset of Landsat 8 Level 1 data, which can be accessed and downloaded through various AWS services.
Google Earth Engine (https://earthengine.google.com/): Google Earth Engine provides access to the complete Landsat archive, including Level 1 data, through their cloud-based platform for planetary-scale geospatial analysis.
While Level 0 data is not publicly available, the Level 1 data products are suitable for most remote sensing applications and have been processed to a level that allows for further analysis and interpretation.
