I'm starting a thread here in Mars Express for a new map of Phobos, because most of it will be based on MEX images.
This is the first section. It's the north pole, centred on the pole, out to 50 degrees north at the edge, in azimuthal equidistant projection (i.e. the parallels of latitude are equally spaced, unlike in a stereographic projection where they would get further apart away from the pole). This image is made of Viking, Mars Express and MRO images. Below it I show what the previous best map looked like, much more compressed to save space here. That is just Viking data, compiled by Damon Simonelli et al. at Cornell in the 1990s. The actual mapping is done at twice this scale.

Thanks for the comments and feedback. Earlier I was using the default IDL fonts and now I'm using the TrueType ones. It's been an interesting challenge to get the font edges to look sharp and do the spherical projection remapping in an efficient manner. So far so good with the latest setup.
The special characters such as umlauts are a bit tricky. With IDL I can get the umlaut to show up when I use the default font and run interactively. However when running in batch mode and when using the TrueType fonts it isn't working so far. So for now I made a version stripping off the umlaut for "Opik".
