Taken from a post on my own website, decided i'd share this here as well
Outerra:
Outerra is a full scale rendering of modern day Earth based on a procedural engine, no cities yet, free for you to explore meter by meter. Really impressive in my opinion.
3D planetary engine for seamless planet rendering from space down to the surface. Can use arbitrary resolution of elevation data, refining it to centimeter resolution using fractal algorithms. Unlimited visibility, progressive download of data, procedural content generation. Integrated vehicle and aircraft physics engines. Embedded web browser for web service integration.

its pretty impressive, in it's alpha stage at the moment. Theres a demo or you can buy the alpha for £10, alpha lets you build roads, place buildings, fly planes and drive vehicles and much more.
"Outerra is a unique 3D rendering engine, a world rendering engine capable to seamlessly render whole planets from space down to the surface. It can
use arbitrary/varying resolution of elevation data that it further dynamically refines using fractal algorithms. The fractals try to mimic natural processes, generating fine, believable terrain with high resolution. The world is also being dynamically textured and populated with vegetation using predefined land type material sets and the computed terrain attributes."
