MAP_SET Aspect Ratio [message #4596] Fri, 02 June 1995 00:00

I have a question about using the MAP_SET function in IDL. I'm
trying to overlay some contour maps onto a specific map projection.
So far, I can plot up everything just fine, but the aspect ratio is
all messed up. When I set the limits, IDL takes those and scales
them to fit the existing plot window, allowing the programmer to
make Colorado 3 miles wide and 600 miles high (not a very helpful
map projection).

Do I really have to tweak the window's scaling factors manually
in order to get a true map projection?

Thanks for your help.
