Feedback from Sarav regarding the polymarker scripts sent out yesterday.
Both examples will be put online, and we will try to add shaded contours
to the basemap as Sarav suggests...

Wow, this is great. I am pretty impressed with the User Support
provided by this group.
Thanks for the scripts. May I suggest that when you post these scripts to
the NCL page, also add a contouring option to the base map that includes
the same color scale.
Best.. Sarav
