polygon area avg?

[Sestak, Michael L CIV 63134]

If you create a grads file with +1 within your area of interest and -1 outside it, you can use maskout to set everything outside your area to undefined and the usual area average commands will only use the data in your area.

Grads users,

Has anyone come up with a way to take an area avg of the area within a
non-rectangle shape? The shape I'm looking for in this case resembles
the shape of Nevada. If not I can probably approximate the shape by
averaging a bunch of smaller rectangles.

Thanks in advance,
Greg
