I'm looking for a recent map ot Titan. Steve Albers's page links to one done by Fridger Schrempp in April 2005. Cassini has done a dozen flybys since then. Does anyone know if an updated map has been released.

Well, I'm still work on smoothing techniques across multiple data sets. I'll admit this one was more of a case of needing to get something out since we haven't had a released map update since January of last year. Unfortunately that's about as cleaned up as I could get it without using destructive low pass filters. The data is already a bit blurry, I see no point in making it worse.

I for one am not underwhelmed by the update as I realized any update couldn't bring much greater resolution than what was already available at Shangri-La. This is probably as high a resolution as we'll get from ISS. One must always keep the expectations reasonable. That's one of the reasons the overdue release delay bothered me, though. That said, I do find the Fensal-Aztlan region to be better defined than Shangri-La. As JRehling said, it appears less grainy. Weren't the pixel scales for the mosaics comparable? Is this a result of different camera parameters / filter combos as the Fensal region looks well defined, albeit including those texture seams? Am I right in assuming you didn't use every flyby that provided repeated coverage (over Fensal), for improved S/N ratio and reduced seaming?

The mosaics used in the Fensal-Aztlan region have a higher pixel scale than those used in the Shangri-la region. Maps incorporating Ta and Tb REGMAP and HIRES should be available in a future release.
