Standardises all layers in a SpatRaster to a scale of 0-1, by dividing by the maximum value in each layer. Only operates by layer

Usage

std_rast(x, reverse, filename = NULL, overwrite = TRUE)

Arguments

x

SpatRaster to standardise

reverse

logical if TRUE will subtract standardised values from 1

filename

Optional character path and filename to write output

overwrite

logical if TRUE will overwrite filename

Value

A SpatRaster with range 0-1
