Digital elevation model — bkg

Retrieve the digital elevation model (DEM) for the territory of Germany.

Usage

bkg_dem(bbox = NULL, interpolation = NULL, epsg = 3035)

Arguments

bbox: An sf geometry or a boundary box vector of the format c(xmin, ymin, xmax, ymax). Used as a geometric filter to mask the coverage raster. If an sf geometry is provided, coordinates are automatically transformed to ESPG:25832 (the default CRS), otherwise they are expected to be in EPSG:25832.
interpolation: Interpolation method to preprocess the raster. Can be "nearest-neighbor", "linear", or "cubic". Does not seem to work currently - despite being listed as a capability of the WCS.
epsg: An EPSG code specifying a coordinate reference system of the output. If you're unsure what this means, try running sf::st_crs(...)$epsg on a spatial object that you are working with. Defaults to 3035.

Value

A SpatRaster containing elevation data.
