Discussion: maps with scale...

Can't you just calibrate it using your GPS?

I figured that issue now but I'm not not sure about how to get the basic contours before I go out and draw more fine contours. Maybe there's some topo map or maybe I can use Google earth's height data to do some basic contours.

Talk to Russell R. He would possibly be able to give you a base map with contours and major features, and correctly scaled and gps located.
