2.11. Landsat radiometric calibration
The tool converts the Landsat raw data into radiation intensity (ToA Radiance).
Inputs:
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.
Outputs:
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)
