Manually entering calibration coefficients

If the input file does not contain the appropriate metadata, you must either manually enter the required information, or import the data from a text file.

Note: If you skip this step, and this information is not available through metadata, the calibration offset and gain are assumed to be 0 and 1 respectively. These values are acceptable for haze removal, but will produce incorrect results for the TOA, cloud masking, ground reflectance, and surface temperature calculations.

To manually enter calibration information:

From the Radiometric Information section’s Calibration coefficients source drop-down list, select Manual Entry.
Click Band Setup. The Band Setup window displays the calibrated coefficients and wavelength for each channel. The number of rows and wavelength information depends on the specified sensor. The Atmospheric Correction workflow is designed to expect image files that are complete and organized, as delivered by the image provider. If the input image contains swapped bands or is missing bands (any other than blue or green, red and NIR), use the Band Setup window to specify which channel contains each band.
In the Band Setup window, specify the Offset and Gain for each band. This information is generally provided with the data set. If your image does not include metadata, contact your image provider.
Click the down arrows in the Channel column to map the channel to the appropriate band.
In the Background Value column, specify the NoData value for each band to define pixels that should be ignored during computation.
Click OK to close the Band Setup window and return to the atmospheric correction workflow.
