The style of this map reminds me of Middle-earth.

Yes, but are there right angles? laugh.gif

Nice!

That piece about the mountains of Middle Earth doesn't hold up when you look beyond the Americas. Check out Siberia, Iran. the vast region north of India, not to mention the Balkans. As a Tolkien fan from long ago and far away, I don't have a problem with his map...or Titan's mountains. Or especially this new map.

What an outstanding work of visualization! Great outreach tool, too. Very, very impressive, Nick. smile.gif

Hey, I don't know if any of you remember me but, I used to drop by once in a while asking for stuff like "reprojected maps of Io" etc.
That was back when I had a weaker computer and Google Earth didn't allow maps to cross the international dateline. Ever since then, I have got a better computer and after the lockdown began, I had time to to update my collection of maps and the Google Earth Solar System overlay. I noticed that there was no updated map combining the ISS map with the HiSAR map but I found some separate ones in USGS Astrogeology. What I did was I got the ISS and HiSAR maps and combined them into one map. Then I added color from the Huygens lander images to the whole globe. The image is 16K so it is suitable for both Google Earth and Celestia.
I didn't do any fancy stuff and the noise from the original USGS maps are still there but it was something I wanted to do since the only map combining HiSAR with ISS was from T71 (July 2010) and it's only 11K B/W.
The map is up to date as of T104 (January 2015)
Here s a link to the full size version. (16K)

How could we forget? Many thanks for making and sharing that. New Titan map products are always welcome.

Very nice to see this Antdoghalo. I wonder how it might look if the radar component is overlain on the ISS-based map from Ian Regan?

This was mainly an experimental thing I did (I didn't think my computer was able to even work on it. It took 20 minutes to complete each task of the process over a few hours but the computer pulled through like the little engine that could). I have since noticed there are some other planetary objects where lower resolution data from older spacecraft could be used to fill in unmapped areas like Phoebe, Charon, and Pluto (which you did a good job adding, Albers). One thing I hope eventually does happen is a map gets released showing radar coverage up to T126 in spring 2017, only then can we have the ultimate updated map of Titan until another probe visits.

I could take a shot at combining Ian's map with the USGS radar map later on this summer.

Well, I combined them and the shading is a disaster between the two maps. While it is nice to have increased resolution (and see a couple more of the North Polar lakes,) its so bad I wonder if simply inverting the brightness would actually make it look better. My computer was barely able to make this hulking monstrosity after a couple crashes with GIMP. Someone with a much stronger computer would have to dedicate a lot of time to eliminating the brightness inconsistencies.

I've tried to look for an updated RADAR map up to T126 prior to mission's end but I cannot find one. The later swaths not included in this one cover a lot of the unmapped areas.

I don't think inverting the brightness is the solution. Making the radar layer partially transparent (50%, or varied a bit to see how 40 and 60 look) might be a better option.

My take at the map in question....There is ISS base overlaid by radar data up to T-104 and false-colored by VIMS data...Can post bigger one in pdf if there is interest...

Here is a near perfect version. (2K thumb of 16K image)
https://www.flickr.com/photos/60012030@N02/...eposted-public/

While making a map of Mars, I discovered a tool in GIMP that was perfect for this. Now it looks like a normal ISS map at first glance but upon zooming in, one would find this map holds a LOT of surprises!!!
BTW, nice color maps Kymani
