it is possible to accurately recreate Earth in Terragen 3?

He has an el cheepo? version at $299.00:

In jis defence he does do some pretty damn nice air craft and the odd auto:

if I pay that price, would only by huge textures
but I'd say it would not be good business ...
if any ask me, this is the best earth model I see in the web
in this case, the artist use Houdini
ironically the only problem of the artist, are the huge textures (my same problem)

Sure Ben, banding. But he has set the bar. Can we beat him?

I'd need to find the data source to start with. I'm assuming it's a public dataset. I don't think it would be practical to use that resolution at a global level as well as a high res DEM, but if you're rendering at a viewpoint where you can see the difference, you won't be looking at a full globe anyway.  Unlike 3DS we're using a georeferenced planet and not just a sphere so we have a lot more flexibility for mixing global and local data sets. 

On the elevation front, I'll see if I can find the link again, but there is a project to do for Earth what HiRise has done for Mars... 2m DEM via photogrammetry.One of their focus areas is Greenland glaciers.

hmmm do not forget that Mars is smaller than Earth
satellite orbits are much lower
is no a surprise to find 2m DEM of mars

a small upgrade
this is how they look some cumulus clouds in my model of Earth clouds
about 70 km altitude (Note that these clouds were not set for this altitude)
I am facing new problems, such as the elevation
and the manner in which the surface seems to "swallow" the clouds, in areas like the Himalayas
as well as also, a new level of orbital realism by adding clouds located in different areas or "sceneries" of Earth
I am also thinking of adding another layer of "localized clouds"
for shots from the ground to the space
and of course, as always, any advice is welcome

Altitude software might help for the range of altitudes

great page of movies...I'd not seen that yet. Thanks Ben.

Yes, it's a good reference for settings.  Not sure how "offset" got changed to "software" in my post. I'll blame TOS

have overcome the problem of altitude with clouds, and now it looks fantastic
I only need add more realistic patterns, large-scale
this is in the same scene

Very promising!

Looking good. Here's a TGD that demonstartes how I'd add the full res blue marble images (First 2 tiles, but you get the rest)  Further to my PM, you can use the PNG images without converting.  The colour adjust and adjust saturation node do nothing in this particular case, but they provide most of the controls you'd need to tweak the colour of the images
