Added Dizin Ski Area, Iran, with lifts

I added Dizin, the best known ski area in Iran complete with lifts. The latest imagery on Google Earth looks like 1 meter resolution for Iran, so it was easy to pick out the lift lines.

The elevation data is pretty bad, though, I guess it’s on 30 meter postings, so you can see the pixels. I recently did Zermatt, Switzerland, and I didn’t check but it must have been on 15 or 20 meter postings, because it was finer than Iran, but not as good as the US.

Since I figured out the bug preventing resorts outside the US and Canada from showing up correctly, I redid the ordering so now North America comes up first, and then the rest of the world. For the Summer I’ll make it where the Southern Hemisphere takes precedence. Might have to do some kind of preferences cookie, too.
