ElevRasterDE: The raster of elevation for Germany

In IsoriX: Isoscape Computation and Inference of Spatial Origins using Mixed Models

The raster of elevation for Germany

Description

This raster contains the elevation of the surface of Germany (meters above sea level) with a resolution of approximately 40 square-km.

Format

A SpatRaster object

Details

This raster contains elevation data of Germany in a highly aggregated form corresponding to a resolution of approximately one elevation value per 40 square-km. This is only for the purpose of having a small and easy-to-handle file to practice, but it should not be used to perform real assignments!

Examples

## Compute crudely the resolution (approximative size of cells in km2)
median(values(cellSize(ElevRasterDE, unit = "km")))

## How did we create this file (without IsoriX) ?

## Uncomment the following to create the file as we did

# ElevRasterDE <- elevatr::get_elev_raster(locations = data.frame(
#                              x = c(5.5, 15.5), y = c(47, 55.5)),
#                              prj = "+proj=longlat +datum=WGS84 +no_defs",
#                              clip = "bbox", z = 3)
#
# ElevRasterDE <- terra::rast(ElevRasterDE)


## How to create a similar file with IsoriX ?
#
# ## Download the tif file (see ?getelev)
# getelev(file = "~/ElevRasterDE.tif",
#         z = 3,
#         long_min = 5.5, long_max = 15.5, lat_min = 47, lat_max = 55.5)

# ## Convert the tif into R raster format
# ElevRasterDE <- rast('~/ElevRasterDE.tif')
