QUOTE (NIX @ May 14 2005, 12:01 AM) Here's an L257 view of Jibsheet. AwalkonMars Still working on the MI mosaic though...  Nirgal, the difference in resolution is indeed an issue but overlapping the images can be a real pain.. Nico  Hi Nico, I just enjoyed your full resolution PNG of east Methuselah (or Jibsheet  ). Exquisite such full resolution! In respect of the size of 25MB I wonder about you generated a PNG-file of it. The orginal pics were sure JPEG - they must be JPEG  Are you sure there would be a visible difference in comparison to a high JPEG version?Note: For the responses in this issue it was opened a new thread in "Imagery & Tech Issues": http://www.unmannedspaceflight.com/index.php?showtopic=1001 This post has been edited by Tman: May 16 2005, 07:55 PM -------------------- |

I think .png is better. Have not tested that extensively though. Anyone? Originals of course .jpg. I'm just used to convert fullres and 50% to .png and thumbnails to .jpg
There's some awesome stereo's in that pan too btw  Nico -------------------- photographer, space imagery enthusiast, proud father and partner, and geek.

I just wanted to see some discussion about the nature of Jibsheet, since it's a rather unusual-looking rock that would seem to be shedding clasts or inclusions onto the ground. I guess I'm a little surprised that none of our other amateur and professional geologists have any opinions about it... -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain
