Compute land cover types

Source: R/compute_landtype.R
compute_landtype.Rd

Compute land cover types around a station based on retrieved topographic data (buildings, roads, water) and digital terrain/surface models (to compute vegetation height and classify: grass, bush, tree) from Kartverket. The horizontal resolution of the digital elevation models defines the resolution of the tile of the topographic data.

Usage

compute_landtype(stn = NULL, f_plot = FALSE)

Arguments

stn

A SpatVector with station attributes from "get_latlon_frost"

f_plot

A boolean whether to plot the land cover types

Value

A SpatVector of land cover types
