Jupiter True Color Texture Map - Cassini — Description
A true color Jupiter map from Cassini data, created by Björn Jónsson: bjj.mmedia.is/data/jupiter_css…

Yes I've done a Cassini map before . I've found that this data was in planetocentric projection. Celestia requires maps of obalte words to be in planetographic projection. As a result, the previous map is squeeced a bit vertically along the equatorial regions. This map in contrast should show the actual vertical pattern of clouds when rendered. Now that I know that, I have to adjust the Hubble and Voyager 1 maps to compensate for this effect.

The original texture is of a somewhat smaller resolution than the NASA texture (2880 pixels vs. 3600 pixels) but it's acutally sharper. So maybe this is the best Jupiter map we have yet. I tried to remove the vertical stripy pattern of Björn Jónsson's texture. What's odd is that after coloring the the texture for a realistic color balance, it is far less brownish than my previous attempts, besides using this texture for relative color reference. I guess this is the result of a low color contrast due to the limitation on only 2 color filters.

Update May 5 2017
I removed the effects of Illumination at the poles and re-adjusted contrast for like the 4th time. I think it now matches Cassini images closely, so giving a most realistic view of the planet. Also color is now more consistent with other maps. Now I can redo the rest of my maps since I used this to fill the unmapped polar areas...
