2.11. Landsat radiometric calibration

The tool converts the Landsat raw data into radiation intensity (ToA Radiance).


  • Landsat band initial File

Processing level L1 file from the original Landsat data archive. The name can be anything. Data can be pre-trimmed, etc.

  • Band number

The band number corresponding to the downloaded file. Usually a number, for ETM + it can also be 6_VCID_1 and 6_VCID_2

  • Landsat Metadata File

Text file from the original Landsat data archive. Depending on the data type, it is a * MTL.txt or * .MTL file.


  • The radiation intensity of the corresponding band in the GeoTIFF format

Radiometric calibration is necessary for time series analysis, calculation of derivative products (for example, index images).

Supported data:

  • Landsat 8 (OLI, TIRS)

  • Landsat 7 (ETM+)

  • Landsat 5 (TM)

  • Landsat 4 (TM)
