I'm working on Spirit at the moment. I will post a few examples of things as I go.
Right now the important job is updating the contemporary route map by locating the stops on HiRISE images. The existing maps at JPL, for the early part of the mission, were plotted on MOC images with inferior resolution and lighting, so I find many locations were about 15 or 20 m out. So at every site I am making circular panoramas (examples later) for comparison with HiRISE. Here's a first example, a map of the route during the Primary Mission. I have added a few extra placenames from the MER Analyst's Notebook at PDS. Phil -------------------- ... because the Solar System ain't gonna map itself.

That last image was from a new study of the rim of Gusev from the pan shot at Everest (Husband Hill Absolute Summit) on sols 620-622. Here is the full panorama turned into a circle. The rim of Gusev has been subjected to an extreme contrast enhancement relative to the near horizon, resulting in artifacts in places. But I think the distant rim has never been seen so fully. Clearer views of small parts of it were obtained from West Spur, but this is the best look at the whole thing. The processing was done from the 16 bit images at PDS. I am working on an identification of features and will post it later, but I think the most interesting thing is the view of the large flat-topped mesas south of the rover, at the supposed Ma'adim Vallis delta, and the hills beyond which extend up the valley a bit inside the breached crater New Plymouth. Vertical exaggeration at the horizon is 5.5x.
