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...

I have a map of Jupiter in 1995 from Hubble. It was before these 3 ovals combined to create what is known as the little red spot (LRS). The 3 ovals first popped up in Jupiter's southern hemisphere below the GRS in the 1930s. They existed til' the late 1990s when they combined with each other.

You probably mean this one: gms.gsfc.nasa.gov/vis/a010000/…
Yes Jupiter's clouds and storms are an fascinating subject. As they are ever chaning, it is interesting to have textures showing them at different decades, corresponding to spacecraft visits.

Yep. There are 3 little white ovals about to merge with each other.
I have a recreation of that texture map in 2 ways.
A regular one for something like Cinema 4D here:
