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.

I've always been surprised that there aren't more amateur Titan ORS mosaics here. (I realise it's a bit of a challenge, but that doesn't usually stop you lot...)

Surprisingly, there aren't a whole lot of people playing around any Cassini images that I can see. Titan would make a pretty hard target to work with, given no easy way to reduce atmospheric haze. You really need excellent flatfields and either you can brew your own ones (hard to do manually) or work with the not so good ones on the calibration volumes. There's a lot to be desired there, especially for the wide-angle camera flatfields which would make simple mosaics easier than taking a shot at high-res NAC footprints. Geometric reprojection would also be handy since the exposures are long and the flybys pretty fast. SPICE kernels in other words...

When the first flybys happened in 2004, I tried my hand at it, with some success, but it was a lot of work to lead to a modest product not that far in advance of the "pro" releases. I attached my work from the first 24 hours of the first flyby in July 2004. I didn't try this again. I used a Hapke map I'd produced for some other world to adjust for phase effects, but I forget which world I had developed the model for. Mercury, I think. Then I just twiddled in Photoshop with no principles but what seemed to look OK. Composite of three ISS frames. |
