Does anyone have a heightfield of the
earth in its entity (only landmasses needed),
or know a functional link where I can down-
load it?
I've already downloaded some of the maps
from NASA, but I'm working on my
"reflective sphere on checkered plane" and
would like to create a fairly nice image of the
earth as the sphere...
Thanks in advance,
Tim
PS: Can't find anything with google, though I
perhaps I don't have the correct words
for searching at hand (topography, heightfield,
earth, image, download)...

The Moray site has image amd Bump maps for the planets.
I don't know if this is detailed enough for you.

They ain't got the heightfield, just the "regular"
satellite photos. What I want is an image where
the highest peak of a mountain is colored white,
and the lowest point of earth colored black, and
in between all grays, you know?

Hm, thats a nice one, but if anyone got any bigger
resolution, I'd be interested. That one is 1024x512.
Thanks for the link though!

Try using DEM files as your source instead

Here is another link
http://www.geocities.com/TimesSquare/1658/earth.html#top
It will involve a bit of work I think maybe too much on top of resurrecting your
dead PC. I was sorry to read about that it can happen to the best of us
obviously.

That link was great! Exactly the kind of images I was
looking for! Thanks!

Hm, looks very complicated to me. Haven't got the time
to dig into that right now, but I'll keep it in mind.

Yup, too much work for the moment.
And you're not implying that I'm one of the best, are you? I personally
think I do pretty fine, but most of my images don't really touch realism,
only some pseudo-realism, where it is still obvious that I'm rendering.
Haven't gotten to the dirt-level yet. :-)

Wow...
I don't see the 21600x21600 images though. I see them mentioned, but no
links that appear to lead to them...and it would be nice if they were
available in a non-lossy compressed format, such as PNG.

Link marked '_Source files_ and technical details (ftp)'
The files are gzipped tiffs.

No to spoil anyones fun, but you do realise that to scale
the earth is smoother than a pool ball :-)

I know, but I've now got a high-res map from which
I can take close-ups or cut certain sections for interesting
heightfields.

So 8 bit grayscale should be more than enough resolution.
You exaggerate the smoothness though...it is very smooth at that scale,
but there are visible irregularities.
