Terms of Use:

  • Landsat datasets are federally created data and therefore reside in the public domain and may be used, transferred, or reproduced without copyright restriction.
  • Acknowledgement or credit of the USGS as data source should be provided by including a line of text citation such as the example shown below.
  • (Product, Image, Photograph, or Dataset Name) courtesy of the U.S. Geological Survey
  • Example: Landsat-7 image courtesy of the U.S. Geological Survey
  • See the USGS Visual Identity System Guidance for further details on proper citation and acknowledgement of USGS products.

Additional Processing

  1. The Collection 2 CFMask algorithm is applied to each Collection 2 Surface Reflectance dataset. The cloud masking attempts to remove medium and high confidence snow, shadow and cirrus clouds using the BQA quality band provided in the Landsat GEE collection. You can read more about the mask here.
  2. The Collection 2 RADSAT mask is applied to each Collection 2 Surface Reflectance dataset. You can read more about the mask here.
  3. Scaling and offset are applied. Band order is changed to align with Landsat 8. Band names are changed to common names. Pan-chromatic band, high gain thermal band, Coastal Band, Cirrus Band are not included.
