I have worked on sprucing up some global views of Europa from Galileo. There are a few more global views I hope to get to eventually. But the best two at nearly full phase benefited a lot.
[Moderator note: There are several more threads containing Galileo Europa images but they all contain several inactive image links.

I've had fairly reasonable results in the past combining low res color (from Bjorn) and hi-res black and white as can be recalled here:
http://laps.noaa.gov/albers/sos/sos.html#EUROPA I've been thinking of redoing this mosaic if I can easily obtain the latest 8K or even higher USGS map of Europa. I understand the bleeding potential though. I wonder if somehow a local color table can be constructed to help with this, if you catch my drift. I'm not really that familiar with fancier methods of colorizing. Steve -------------------- Steve [ my home page and planetary maps page ]

I've been thinking of redoing this mosaic if I can easily obtain the latest 8K or even higher USGS map of Europa. A 500 m/pixel (19631 x 9816 pixels) version is available at the USGS website and it should be geometrically very accurate. Interestingly, it doesn't include some observations that could have been used to increase the resolution in some parts of the map, for example the 14ESTYREHR01 and 14ESWEDGES01 observations and some of the G7 observations. I'm using all of these in the map I'm working on (which has now grown to 20000 x 10000 pixels). In total I expect to use approximately 200 Galileo and Voyager images. |
