Now you can see the map in QGIS project as a georeferenced raster. Note that the raster seems to be slightly
rotated, but that is simply because the data is KKJ / Finland zone 2 and your project is in ETRS89 /
ETRS-TM35FIN.
To check that your data is properly georeferenced you can open the aerial image in the
exercise_dataforestry folder, named rautjarvi_aerial.tif. Your map and this image
should match quite well. Set the map transparency to 50% and compare it to the aerial image.
