[ncl-talk] GKS contour problem

[Rick Brownrigg]

Its very hard to say from just inspecting your script. There are multiple
places where corners appear to be set, many of them commented out, and the
readers here are left to wonder which were in effect at the time the error
messages would occur. It does sound like the corners specification is not
correct -- I would print values everywhere.

I would also note that the setting for the resource mpLambertParallel2F is
not a valid value for latitude -- this looks like a setting for
mpLambertMeridianF. I don't know if this is enough to confuse the
projection algorithm or not. Maybe fix this first before trying anything
else?
