Wavelength-range definitions for infrared radiation according to ISO, CIE or as commonly defined in remote sensing applications.
Usage
IR(std = "ISO")
NIR(std = "ISO")
IRA(std = "CIE")
SWIR(std = "CIE")
IRB(std = "CIE")
SWIR1(std = "RS")
SWIR2(std = "RS")
MIR(std = "ISO")
IRC(std = "CIE")
FIR(std = "ISO")
TIR1(std = "RS")
TIR2(std = "RS")
Details
The values for std = "ISO"
are according to ISO 20473. The values for
std = "CIE"
are suggested values according to Wikipedia, and need
verification.
The wavelength limits for remote sensing std = "RS"
and for
Landsat imagers have been obtained from R package 'RStools' and NASA and USGS
documentation.
The names NIR, SWIR and TIR are abbreviations of near infra-red, short-wave infra-red and thermal infra-red, respectively. The naming conventions are different for "CIE" than "ISO" standards, and the labels of the waveband objects reflect this with "IRA", "IRB", etc., used when appropriate.
