The largest volcano in the solar system "Olympus". In work were used 3dsmax, pscs3, satellite photography, manual heights map. "Mount Olympus - the extinct volcano on Mars, located in the province of tharsis mountains, the highest mountain in the Solar system. Olympus takes so much space that you can't see it completely from the surface of the planet (the distance is required to view the volcano, was so great that he will be hidden because of the curvature of the surface). Therefore, a complete profile of Olympus can be seen only from the air, or orbit. Accordingly, if you stand on the highest point of the volcano, the slope will go beyond the horizon".
