I could never figure out what the maps were indicating when i was little. So i made one that i would have been delighted with as a kid.

As you print, if you don't have an automatic color changing system, I have implemented a few stops, based on height where you can change the color. It always goes Green, Yellow, Brown, White. This is the method these photos were achieved with.
