Normalized Burn Ratio 2 {LSRS}

Normalized Burn Ratio 2

Description

The Normalized Burn Ratio 2 (NBR2) is calculated as a ratio between the SWIR values, substituting the SWIR1 band for the NIR band used in NBR to highlight sensitivity to water in vegetation.

NBR2= (SWIR1 - SWIR2) / (SWIR1 + SWIR2)

Usage

NBR2(a = "SWIR1", b = "SWIR2")

Arguments

a

SWIR1 satellite band (Wavelength:1.566 - 1.651 micrometer) (format:TIF)

b

SWIR2 satellite band (Wavelength:2.107 - 2.294 micrometer)(format:TIF)
