Ian,
Wow, those maps are fantastic! Thank you for showing us your long hard work. The explanation of how you did it, is inspiring. You are one cool cat! -------------------- CLA CLL

Agreed! These are beautiful.

Thanks everyone for the positive responses. As I'm sure you can imagine, this data was an absolute bear to work with, so although room for improvement undoubtedly exists, I'm generally delighted with the results.
I intend to post versions incorporating the SAR radar data (perhaps colour-coded? I'm undecided on the exact presentation.) But for now, here are those three image products again, this time merged with topographical information from a paper by P. Corlies et al: Cassini ISS Titan Mosaic & Topography: Equatorial View (USGS/Ian Regan/P.Corlies et al.) Cassini ISS Titan Mosaic & Topography: Northern Hemisphere (USGS/Ian Regan/P.Corlies et al.) Cassini ISS Titan Mosaic & Topography: Southern Hemisphere (USGS/Ian Regan/P.Corlies et al.) Blue areas represent low-lying regions up to -1,800 metres below the average. Red areas indicates peaks of up to 650 metres. -------------------- |

Let me add my voice to the chorus of ...incredible work, Ian.
Interesting that there's a high region (...for Titan; pretty flat place, really) adjacent to the north polar sea complex. Gotta wonder if that provides orographic lift & enhances precipitation to feed them. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

Thanks for the amazing maps Ian. Titan, being the Hydrocarbon Moon, is rather beautifully rendered like a colorful oil sheen!

Awesome maps and clearly a lot of work that was required to complete them. Titan isn't exactly the easiest 'image processing target' to work on.

Ian R Magnifico! You did what I always wanted. I was hoping for these maps !!
This is the most fascinating world after the Earth. No doubt. The missions to observe Ligeia mare or Kraken sea closely are my dream, for my most important opinion of some primary mis-seals on Mars. This is my Ligeia mare model 12x17 cm. Handmade. No 3D printer. I know, it's not perfect. http://antidotumtarantulae.altervista.org/...are_Ligeia.html What color would you think of ethane-methane seas? I maybe I had to do this sea in black? |

Perhaps a deep, black-ish-brown would be the right colour? Even so, it still looks great Daniele!

Another exercise in seam removal, but this time applied to stacked radar data from multiple Cassini flybys:

And this one might be of interest to Daniele

My goodness Ian those are phenomenal. Do you have plans to make more? I feel like I've never seen the lakes this clearly.

That map of Ligeia is amazing. I like how visible the river that flows into NE Ligeia is (can see that in ISS data)

Ian, so much good work in every one of these products.
If I may, here is a brightened version of the Ligeia image, to emphasize details within the lake. It's clear that the channels continue well past the current shoreline, which would seem to indicate a lower surface level in the past. |
