How do you accurately model elevation?

So I have TS2014 with Google overlay working. It's awesome.

But I'm doing a real-world mountainous place, and I'm having a bugger of a time getting elevations right. I do have documentation on all the rail grades, so thankfully that is not an issue. Just the surrounding terrain.

When the system speaks of elevation units, are those in meters? If I must I can get elevations from Google Earth directly and translate that to units in the game, but I have to know what they are.

Is there a best-practice, or is it mostly guessing?

This only answers one small part of your question but yes it's in meters and I believe under settings in Google Earth you can change the settings there to meters.

Have you read these?

That's good. I just saw the information on importing terrain data. I might do that and save myself years of my life (if I can get it to work).
