Import and plot raster data
In this exercise, we are going to use a raster dataset of the vegetation types map (available from https://www.wri.org). The raster values take a set of discrete values indicating the type of vegetation. Let's start with reading the data and plotting it together with the mining site data.
The mining sites dataset (mining_sites
) is already loaded, and GeoPandas and matplotlib are already imported.

Anleitung zur Übung
- Import the
rasterio
package. - Open the vegetation map geotiff file (
"central_africa_vegetation_map_foraf.tif"
) and assign it to a variablesrc
. - Plot the raster dataset using the
rasterio.plot.show()
function and add the mining site locations in red and marker size of 1.
