NBR2: NBR2 - Normalized Burn Ratio 2

Description

NBR2 modifies the Normalized Burn Ratio to highlight water sensitivity in vegetation and may be useful in post-fire recovery studies.

Usage

NBR2(SWIR1, SWIR2)

Arguments

SWIR1

A raster layer object with the reflectance values for the Short Wave Infrared 1 band.

SWIR2

A raster layer object with the reflectance values for the Short Wave Infrared 2 band.

Value

NBR2 - Normalized Burn Ratio 2.
