3D terrain of the France was created in Cinema 4D R23 based on a high-polygonal STL model.
The height of the 3D model was increased by 10 times, so that the relief did not seem very flat. You can adjust the height as you want.
UV-map in frontal projection was created for correct texture mapping. Textures can be edited in Photoshop and returned to Cinema 4D.
The built-in physical renderer in Cinema 4D was used to produce the images of France.
