This mine is the first thing I zoom in on when checking out a new procedurally generated 3d world map service. It is easy to spot because of the nearby Vilyuy Reservoir built to power the mine. Everyone's algorithm can handle mountians, but I've yet to see one that correctly renders this crater. Even google earth shows the mine as flat.

Not sure, but maybe Google is just using some readily available set of topological data? The hole, being man-made, would display as flat in the same ways that do the buildings of Mirny.

I know for a lot of places, Google use fancy algorithms for extracting information about buildings and trees, and those algorithms never cease to amaze me. Anyway, Mirny is clearly not one of these places.

Don't tempt us with interesting details like that and then leave out the name :)

S/he gave an example already--Google Earth. Apple Maps also has generated 3D maps.
