A 4k moon map is now available at Celestial Visions. Thanks Ras.
Why not 8k ?
- This file would have a size of 12Mb and i have only a modem connection. A higher compressed file suffer a significant quality loss.
- The visible improvment is small. Beliefe me! All my shots made with 4k maps. Together with a 4k normal map you will not see a significant improvement.

If there is an interest i will ulpoad my 4k normal map (not small in size).

Fridger, my old moon map looks similar and i was not happy with this.

I think that the most realistic Clementine map is the albedo map; the ones with shadows from surface features don't make nearly as good textures. Unfortunately, even the albedo maps have shadows in the polar regions, since the sunlight there is always oblique.

I'd like very much to have the normal map that you used. Please do make it available.

Here is a short status report on some work I did to improve existing
4k, 8k hires moon textures. Unfortunately, the hires PDS MAP-PLANET data
have lots of nasty artifacts. This also includes Jens' 4k
texture above. Notably, there are bad stripes in the 4k,8k raw
textures as well as lots of dark rectangular marks both in the 4k, 8k grayscale
textures and in the available hires albedo maps. Like so:

So as to my standards at least: lots of work ahead;-).

Here is a taste of what I did so far. I used this Apollo13 photo

to colorize the 4k and 8k Celementine (PDS) textures, after having
/destriped/ them thoroughly with GIMP! The 8k still needs some
elimination of the dark rectangular marks, but that's just a matter of
(spare) time...

Here is how my 8k moon textures with carefully generated 8k normal
maps presently look like. Compare the colors with the Apollo13 photo...

I hope I will be able to make a complete
update of my Celstia Texture Foundry site with entirely new and very
nice textures very soon..

Bye Fridger

Hi Fridger,

These shots look awesome! I'm looking forward to an update of your site, also because of your earth normal map. I did not succeed yet to produce a good one. I hope you will find an opportunity!
