Following in Christoph's footsteps here... I'm rendering the other (current)
Mars rover's landing site, plus dust storms. Proposed target should be a
little down and right of center in this image (dust clouds over area too).
Not a very close view at all, since this covers many degrees of longitude
and latitude.

The image and elevation maps I used for this can be found at
www.space-graphics.com , a great place I stumbled across when looking for
free non-commercial high resolution images.

Looks good, the clouds are a nice addition although they seem a bit 
yellow in comparison (the planet surface looks very blue on the other hand).

As a general note: it is quite funny how strongly the various views of 
mars you can find (real photographs as well as renders like this) differ 
in the colors.

Too much green in them from what I can tell when I post-process to adjust
it. I was trying for brighter and yellower appearance though, to
differentiate it from the undisturbed ground. The bluish cast is actually
clouds and ground fog, it just happens to cover so wide an area it looks
like part of the surface. The image map used has such a strong orange
coloring it is very noticable when compared to a rendering without the
atmosphere.

Yes, there's so many ways Mars is shown I didn't use a real reference as
guide. Now that I go looking for one, what I had in mind was something like
this:

And here's a great Hubble photo showing both the blue-white clouds and
yellow-orange dust:
http://www.news.cornell.edu/Chronicles/7.26.01/Mars.html

There are some photos showing so much cloud-cover it looks strange after
being so accustomed to atmosphereless renderings and other pictures.

Thanks for the URL, to those MOLA files, you gave in the other thread.
Although I had seen it already within the past few days I didn't know what I
could do with the IMG file type. In fact, I still don't. I'm downloading two
of them now (~240MB) and my 2Mbps connection isn't helping speed that up a
whole lot with them going about 70Kps.

Hmm, now that I have these two img files I can't open them as GEM raster
files, Irfanview suggests they are JPG and stops after renaming with an
error about incorrect JPG "SOS before SOF".

Oh, nevermind... I'm using 3DEM (
http://www.visualizationsoftware.com/3dem/downloads.html ) to view the IMG
and then save as a bitmap. As you can see, I'm doing all this while
replying. The resolution looks real fine.
