Marble: Create a map of the Saturn moon Titan for Marble

Marble can visualize maps of the earth as well as for other planets. So far we only offer maps for Mercury, Venus, Earth, Mars and the Moon. But there is also some map material available for Jupiter and Saturn Moons.

This task is about creating a map for Titan that displays Titan's surface. You can use the texture data from Wikipedia:

Texture Map

Cut out the actual map part carefully using Gimp or Krita (accurate to the pixel).

Then the data needs to be integrated: For this you need to create an xml file in the "dgml" format. Please download the "Thomas Harriot 1607 Moon Map" zip file as an example here:

Marble Maps

This Thomas Harriot moon map should serve as a template of what a good map theme should look like.

Unzip it and have a look at the dgml files. Find out which changes you need to create the map for the moon.

After editing the file it should be possible to display Titan inside Marble.

However it's still missing labels for place names. These can e.g. get downloaded

from here:

Planetary Names USGS

Inside the marble source code you'll find a conversion script that worked for earlier use of this website. It might need to get updated to work properly again.  Also make sure that the longitude matches the surface features on the texture (it might be shifted by 180degs).

The result of the conversion should allow the map to display places on Titan. The symbols for each item on the map should match the symbols in the legend.

Add some interesting information to the legend (like done for the Thomas Harriot moon maps  from 1607 in Marble): Check out information about landing missions on Titan. Why is Titan of interest to space science?

At the end of the task the student needs to verify whether the data displayed is consistent with other sources on the internet.

The expected result of this task is a full blown map of Titan displayed in Marble that uses the proper symbols for for all surface features on it.  This map needs to be provided in a way so that it can get uploaded to Marble's GHNS server.
