Far_red: Constructor of FR waveband

Description

Far-red radiation according to "ISO" (not defined) or as commonly defined in plant photobiology, "Smith10" (725-735 nm), "Smith20" (720-740 nm), "Inada" (700-800 nm), "Warrington" (700-850 nm), and "Sellaro" (700-750 nm). The red-edge used in remote sensing of vegetation is centred at the reflectance transition in the far-red band (725 nm), we define "RedEdge40" (705-745 nm) and "RedEdge20" (715-735 nm).

Usage

Far_red(std = "ISO")

Arguments

std

a character string, defaults to "ISO", as for other colour definitions, which in this case returns NA.

See Also

NIR for wavebands close to the boundary between red and infrared regions.
