Scale a SpatRaster object values to a range between 0 and 1

Scale a SpatRaster object (from the terra R package in) values to a range between 0 and 1.

Usage

Scale_0_1(x)

Arguments

x

SpatRaster; The SpatRaster object to be scaled.

Value

SpatRaster; A SpatRaster object with all values scaled between 0 and 1.

Note

This function takes a SpatRaster object as input, calculates its minimum and maximum values, and scales all its values to a range between 0 and 1. This is useful for normalization purposes in spatial analysis and modeling. The function relies on the terra package for spatial data manipulation.
