The functions above return the following information:
lutInfoBandsFromSID
returns the band info block.
lutInfoBCDEFromBID
returns the band code.
lutInfoBIDFromBCDE
returns the band ids.
lutInfoRSRromSID
returns the relative spectral response (rsr)
for the sensor.
lutInfoSensorFromSID
returns the sensor name.
The LUT contains the following band information taken, if not specified otherwise, from the USGS Landsat FAQ:
Minimum/maximum wavelength for Landsat 4 bands.
Minimum/maximum wavelength for Landsat 5 bands.
Minimum/maximum wavelength for Landsat 7 bands.
Minimum/maximum wavelength for Landsat 8 bands.
Landat 7 rsr (nm-1) taken from the spectral viewer of the USGS Landsat FAQ.
Landat 8 rsr (nm-1) taken from the spectral viewer of the USGS Landsat FAQ.
Solar irradiance (W m-2 nm-1) taken from the National Renewable Energy Laboratory.
Tabulated ESun values from tab 11.3 (Thuillier spectrum) of the Landsat7 handbook.
Tabulated ESun values from Chander G, Markham B (2003) Revised Landsat-5 TM radiometric calibration procedures and postcalibration dynamic ranges. IEEE Transaction on Geoscience and Remote Sensing 41/11, tools:::Rd_expr_doi("10.1109/LGRS.2007.898285").
