Description
Convert MSS DN values to TOA reflectance.
Usage
1
MSSdn2refl(imgFile)
Arguments
imgFile
filename (character). Full path to *dn.tif image file produced by the MSSunpack function.
Details
DN values are first converted to top-of-atmosphere (TOA) radiance using the equation found here.
Then TOA radiance is converted to TOA reflectance using the equation found here.
The ESUN values used are from the publication 'Chander et al. 2009. Summary of current radiometric calibration coefficients... Remote Sensing of Environment. 113'.
Value
A 4-band Landsat MSS GeoTIFF raster image file in units of top-of-atmosphere (TOA) reflectance. The file will be placed in the
same directory as the 'imgFile' with the name equal to the image ID followed by 'toa_reflectance'. Note that the values are scaled by 10,000
and rounded to the nearest integer to reduce the file size.
