From Kyle Lochhead and Tyler Muhly's CLUS road simulation example. SpatRaster
files created with the terra package must be saved with terra::wrap() and
need to be unwrapped before they are used. prepExData() is provided to do
this.
Usage
data(CLUSexample)Format
A named list where: $cost is an object of class PackedSpatRaster representing road cost, $landings is an object of class sf representing landing locations and $roads is an object of class PackedSpatRaster representing existing roads
