Here's a heightmapped terrain model of my hometown city Graz in Austria.
It includes the area around the city, the main albedo texture was created by me by stitching together satellite pictures of the area. The model also includes a normalmap and heightmap. For artistic purposes I exaggerated the height of the model, it can easily be corrected by scaling along the height axis though. Have fun and let me know if you use the model for anything, would love to see it :)
Software used: Blender, Photoshop and various other softwares for generating heightmaps and satellite images
