a quick run through isis3's "dstripe"
just a first guess , and still needs a bit of work a crop of http://pirlwww.lpl.arizona.edu/~perry/RADA...T059S01_V02.jpg without denoising first , "dstripe" tacks care of most of that ------ for that i tend to use gmic CODE gmic BIUQH67S152_D201_T059S01_V02.jpg -type float -remove_hotpixels 2,1.0% -type uchar -o BIUQH67S152_D201_T059S01_V02.Less.Noise.png that line removes most of the " salt&pepper " |

Much thanks JohnVV for above. Have used your image to modify my T59 snippet map on the previous page. Must confess I am a Windows user and not familiar with isis. Is there a destripe type plugin for ImageJ?

Preliminary global map of Titan. Version 0.2.0.

Beautiful work, Machi! It's a challenge to get the very low-res topographical data merged with the albedo map, but your result is thought-provoking. With my Titan map/globe, I skipped the topographical data to focus on the color, but the topography is definitely worthwhile as well. With better data, a map could provide all three, but low-res topography doesn't lend itself, I guess, to being demonstrated through shading.

Yes! All your maps are really nice, and this superb combination of datasets is very useful, especially since there really is nothing else like it.

Thanks Phil!

With better data, a map could provide all three, but low-res topography doesn't lend itself, I guess, to being demonstrated through shading. Yes, merging elevation data with SAR/ISS map was maybe the most difficult part. Elevation data have very low resolution (1 or 2 pixels per degree) so topography shading is effectively impossible. So this isn't topographic map, it's SAR/ISS map with overlaying low-res elevation data (BTW, the same data which Ralph Lorenz used in his first ever topographic map of Titan). I also wanted to include VIMS data as in your very nice map but there isn't yet VIMS map with quality which I need. -------------------- |

Great map Daniel! I'm only browsing on a mobile device, but even so, the quality and sheer level of detail are clearly evident.

Do those maps contain SAR radar data after June 7, 2012?
I have seen no Full swaths released after that date. |

I've noticed that as well. I check Jason Perry's SAR site from time to time but the flow of new data appears to have stopped.

This USGS mosaic contains all radar swathes up to and including the August 2014 T-104 data return:
http://astrogeology.usgs.gov/search/detail...n180_128ppd/cub I used this mosaic and combined part of it with a cleaned and de-seamed and colorized ISS mosaic to produce this dynamic view of Adiri: Adiri — Mountainous Plateau of Titan by Ian Regan, on Flickr -------------------- |

Yeah, I haven't been keeping it up, mostly because the RADAR team now includes JPG versions of the SAR swaths in the Extras section of their PDS releases, as Ian R links to. -------------------- &@^^!% Jim!

Those are images, not maps. Maps are derived products from data such as this.
Just quibbling a bit.... -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/
