Actually, you hit the nail mostly on the head. I used a lot of "borrowed" earth coastlines when I came up with the map based on everyone's comments. I used Google Earth, Photoshop, Corel Painter and a couple of other pieces of software on my Mac. For instance for the coastline of the Canim continent, I used some coasts from Norway and Sweden. I went to South Africa for the southern coasts of Alera. I picked up an isthmus from somewhere, don't remember which one but it seemed to work. Things like that.
I used Google Earth a lot to do these things. Why reinvent the wheel unless the topo is so outrageous that nothing "real world" would fit it.
Haven't looked at Eragon. Is it really bad?

Interesting POV, I hadn't really thought about whether physics should be a rule. Furies are not in our physics, after all. But the Aleran sky is blue & grass is green and north is cold & south is hot, so I automatically assumed that water runs down hill and went right on from there. Funny how your worldview gets brought along for the ride...
If you want to look at a map that REALLY gets me twisted, go look at the one for Eragon (shudder).
I wonder if bits of Earth could be cobbled together to put the right scene elements in the right places AND still have the right physics. Google maps & Photoshop, what fun!
