extrapolation_zones: A simple function to map extrapolation zones

Maps strict extrapolation zones

extrapolation_zones(M_calibra, G_transfer, as_vec = FALSE)

Arguments

M_calibra

An object of class SpatRaster or a matrix of predictors for the calibration area (M area in ENM context).

G_transfer

An object of class SpatRaster or a matrix of predictors for the transfer area

as_vec

Logical. Whether return cell ids of extrapolating pixels or not

Value

Returns a binary map showing strict extrapolation zones (ones). If the parameter as_vec is TRUE, the function return pixel ids of strict extrapolation.
