Simulated DEM for testing local metre stem maps

Builds a small elevation raster in the same 0-100 m local coordinates as geo_example_stems(), for testing topographic backdrops in plot_topo(). The surface is a formula, not a survey: use a real DEM (for example geo_elevation()) for figures.

Usage

geo_example_dem(res = 2)

Arguments

res

Grid resolution in metres.

Value

A terra::SpatRaster.
