BSI: BSI - Bare Soil Index

In nightmares: Common Analysis with Remote Sensing Data

Description

BSI can be used for soil mapping and crop identification. This index relates the Blue, Red, Near Infrared and Short Wave Infrared bands.

Usage

BSI(B, R, NIR, SWIR1)

Arguments

B	A raster layer object with the reflectance values for the Blue band.
R	A raster layer object with the reflectance values for the Red band.
NIR	A raster layer object with the reflectance values for the Near Infrared band.
SWIR1	A raster layer object with the reflectance values for the Short Wave Infrared band.

Value

BSI - Bare Soil Index.

Examples

library(raster)
path_files <- system.file("extdata/", package="nightmares")
bands <- stack(list.files(path_files,".tif", full.names=TRUE))
x <- ref_oli(bands, sun.elev= 67.97)
BSI(x[[2]], x[[4]], x[[5]], x[[6]])
