This model was rendered using MATLAB R2016a on topographic map from Schenk
(2008), made with the images from the Voyager mission. When the Voyager 2 probe flew by the Uranian System, tooks very few pictures of Ariel. About a half of its surface is known, so the topography that can be deduced from photometry is reduced to a little patch. The rest was filled by interpolation.
The file's names explained: name_1_x_10_y.stl is 1 : x * 10y. So _1_6_10_7 is 1:600000000 or one in 60 million.
P. M. Schenk. Cartographic and topographic mapping of the icy satellites of the outer solar system. 2008 .
Ariel is the second least bigger of the five biggest Uranian satellites and the second in distance from Uranus, after Miranda. Like the rest of the big moons it orbits at the plane of Uranus, which is nearly perpendiculary inclined from the Solar System Plane. when the Voyager 2 made the flyby of Uranus, its south pole was pointing to the Sun, so only the south hemisphere was visible. Like most of the big icy moons in the Solar System it is hightly deformed because its proximity of its parent body.
