Circuit Map Data

[Moose]

Does anyone have any good sources of map data for circuits? I think I can get good lat/lon sources from OpenStreetMap for most circuits, but there are some notable omissions.

- Baku (though, mostly because I don't know which streets are used, can someone point it out?)
- France (again, since I don't know exactly which pieces of Paul Richard are used, anyone able to point it out?)
- Sochi
- Mexico (though perhaps the search is failing, Circuit Hermanos Rodregiuez takes me to what appears to be a carting track)

What I'm definitely lacking though is the z axis - does anyone have a good source of elevation data for these circuits?

I don't need mega accurate data - the intention here is to carve wooden maps of each circuit to hang on my wall, but I do need enough data to produce something close enough to reality at a 1:2500 to 1:5000 scale.

In google earth, if you create a path, you can show the elevation profile along it.
