MNDWI: MNDWI - Normalized Difference Water Index

Description

MNDWI can enhance open water features while efficiently suppressing and even removing built-up land noise as well as vegetation and soil noise.

Usage

MNDWI(G, SWIR1)

Arguments

G

A raster layer object with the reflectance values for the Green band.

SWIR1

A raster layer object with the reflectance values for the Short Wave Infrared band.

Value

MNDWI - Normalized Difference Water Index

bands <- stack(list.files(path_files,".tif", full.names=TRUE))
x <- ref_oli(bands, sun.elev= 67.97)
MNDWI(x[[3]], x[[6]])
