Been developing a pipeline to get these things with a click of a few buttons. Spent like 8 hours working and researching to get it done with terragen2 and other apps.
Now I can render these out rather quickly tho the resolution requirement increases render time a lot..
Expect more of these in the future!
And yeah as Tadp0l3 said I think I need to point out that its a flash file and you can pan around xD
Please note that this is just a test and not an actual proper work

How does one get a screenshot of particular angle?

And great work.
