Hi! I made this for cycles renderer. Content is created from height maps: From real world data, in this case from planet mars surface. Real craters are Gale crater,mars crater,mars crater 2,(i do not those craters real names thats why "mars crater" etc). And surface model of Valles Marineris. Last but not least is Olympos Mons volcano model. In real life Olympos mons is largest volcano in our solar system. Height is 25km/16 miles. Vallis marineris is 4000 long and 200km wide. You can get more details if you add dirt and couple displacement modifiers. Have fun with these models.
