# 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

 `1` ```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

 ``` 1 2 3 4 5 6 7 8 9 10 11 12 13``` ```## 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")
}
