Arrakis scaled one in sixty million

This post is based on this official map of Arrakis (suggested by the user Joy Cohn), from the Frank Herbert's Dune saga. 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* 10^y. So _1_6_10_7 is 1:600000000 or one in 60 million. 

The size of Arrakis

There are a good reference of the size and other characteristics of the planet since the big background of the Dune saga, provided by the book "Dune Encyclopedia". 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 and 201 km in diameter respectively. They are too small to make in the same scale as Arrakis.
