I created my own hand topographical map from this image, and then I used MATLAB R2016a to plot the topography in spherical coordinates, interpolating the missing areas in a similar way I have done with other astronomical objects. I made also a "flat arrakis" or "board" version using the entire topography. 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.

Arrakis, Dune, Rakis, is a planet about the size of Venus, with a composition similar of that of Solar System rocky planets. However the distances described on the books are far shorter than the represented on the map. It has two moons: Krelln and Arvon of 488 km an
