NBR2: Normalized Burn Ratio 2

In LSRS: Land Surface Remote Sensing

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)

Examples

## The function is currently defined as
function (a = SWIR1, b = SWIR2)
{
name=NBR2(a,b)
areaXY <-c(xmin, xmax, ymin, ymax)
cropXY <- crop(name, areaXY)
plot(cropXY,lwd=4,
     main="NBR2",
     xlab="easting", ylab="northing")
hist(cropXY,
     main="NBR2"  ,
     xlab="NBR2",col="red", ylab="Frequency of Pixels")
     }

Example output

function (a = SWIR1, b = SWIR2) 
{
    name = NBR2(a, b)
    areaXY <- c(xmin, xmax, ymin, ymax)
    cropXY <- crop(name, areaXY)
    plot(cropXY, lwd = 4, main = "NBR2", xlab = "easting", ylab = "northing")
    hist(cropXY, main = "NBR2", xlab = "NBR2", col = "red", ylab = "Frequency of Pixels")
}
