Calculate Moisture Stress Index (MSI)
Description
Computes the Moisture Stress Index (MSI) from SWIR1 and NIR bands.
Usage
calc_msi(swir1, nir)
Arguments
swir1
Short-wave infrared 1 band (terra::SpatRaster or numeric).
nir
Near-infrared band (terra::SpatRaster or numeric).
Details
MSI = \frac{SWIR1}{NIR}
Value
A terra::SpatRaster (named "MSI") or numeric vector with index values.
