R Documentation

Get or access internal LUT values used by various functions

Description

Get internal look-up table (LUT) values from sysdata.rda which have been compiled using data-raw/lut_data.R. Metadata is stored in lut$meta.

Usage

lutInfo()

lutInfoBandsFromSID(sid)

lutInfoSensorFromSID(sid)

lutInfoBCDEFromBID(sid, bid)

lutInfoBIDFromBCDE(bcde, sid)

lutInfoRSRromSID(sid)

lutInfoSIDfromFilename(files)

lutInfoSGRPfromFilename(file)

Arguments

`sid`	Sensor id as returned e.g. from `lutInfoSensorFromSID`.
`bid`	Band id as returned e.g. from `lutInfoBIDFromBCDE`.
`bcde`	Band code as returned e.g. from `lutInfoBCDEFromBID`.
`files`	Filename (or filepath) of one or more remote sensing data filenames
`file`	Filename of a remote sensing data file

Details

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:

l4_band_wl: Minimum/maximum wavelength for Landsat 4 bands.
l5_band_wl: Minimum/maximum wavelength for Landsat 5 bands.
l7_band_wl: Minimum/maximum wavelength for Landsat 7 bands.
l8_band_wl: Minimum/maximum wavelength for Landsat 8 bands.
l7_rsr: Landat 7 rsr (nm-1) taken from the spectral viewer of the USGS Landsat FAQ.
l8_rsr: Landat 8 rsr (nm-1) taken from the spectral viewer of the USGS Landsat FAQ.
solar: Solar irradiance (W m-2 nm-1) taken from the National Renewable Energy Laboratory.
l7_esun: Tabulated ESun values from tab 11.3 (Thuillier spectrum) of the Landsat7 handbook.
l5_esun, l4_esun: 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, \Sexpr[results=rd]{tools:::Rd_expr_doi("10.1109/LGRS.2007.898285")}.
