Good stuff.  I came across these guys quite awhile ago: http://photosculpt.net/ They do similar stuff.  I have a few of their textures but I think its beyond TG's capability to perform it.

The sand looks great man, how much of the lighting is baked in the color info?

Not much - I scans only with very diffuse light - on cloudy days or simmilar. So you can perfectly relight from every direction.
There is also a AO-map designed by the scan-depth-information - if you add this inverted to the diffuse you can light up the parts that are naturally darker - but I would not. The demos are relative simply shaded - no filters no layers

Thanx a lot for the great response wink
I planed a pack of 30 surfaces - should be ready in within a month.
Of course there will be free demos for testing
.
I'll keep you informed.
emphasis mine

I would like to know more about the exact process, even more than I want to get my hands on the demo textures... Which I do want to get a look at.

This is the type of realism that i drool over.

I keep checking back on this. No release yet. But here is his portfolio if you missed it. https://www.artstation.com/artist/chris-3d

Not sure how you can us this in tg. But lets have a look shall we?

I also found this the other day which is related in the 3D scan and displacement area.

Here is a TG test of the demo texture on TG rock object.


I am very curious about what normal maps could do in TG if they were supported? Of course this test is all bump. Real displacement explodes the TG rock object and ruins the lighting.

You have to enable Smooth Normals for it not to explode.

Oh yeah, forgot about that conversation. Ill try it after this render is finished. I applied the textures to the tg terrain. Looks pretty good. But I think the river stone textures and the sand textures in the op would be much more fun to play with!

Here is the TG terrain ground test. Worked really well I think. Of course I am not doing anything that has not been done before, other than trying this guys textures in TG. But I am am having fun for no reason at all. So  :)

K, board with it now  ;D But here it is. Could easily make it better, but as I said...

15min render, color corrected.

It does not look as clean as the renders at that site so i have to wonder if terragen is doing something internally to the texture maps?

just lower the displacement value is all. I set it higher than they would have. The first object test about with real displacement shows it more like it was meant to look.
