contouring into continents only [message #31813] Mon, 19 August 2002 00:30

Hi all.

I'm desperately trying to draw contour lines inside continental boundaries
only (I have irregularly gridded precipitation data). I have test several
'brute force' methods (as creating a mask of 1 over land and 0 over seas)
but none seems to work properly.

Is there any easy (as any esoteric keyword unknown to me) method to do that?

thank you!
David
