Arguments

NIR	Raster of near infrared band from Sentinel 2
SWIR	Raster of SWIR 1 band from Sentinel 2
SWIR2	Raster of SWIR 2 band from Sentinel 2

Value

Examples

#load bands, need to resample from original image, NIR = 10m, B10 = 60m, B11 = 20m
NIR <- raster("B8Sentinel.tif")
SWIR <- raster("B10Sentinel.tif")
SWIR2 <- raster("B11Sentinel.tif")

#excute command
AS1sentinel(NIR = NIR, SWIR = SWIR, SWIR2 = SWIR2)
