<DIV>I will provide a response later on this evening when I have more time
outside my work hours. It might also help if you send me a copy of your

images. That is definitely leading me down the right path. I have
attached my attempt to reproduce your work, called test_4.png. Please
note, that is only a work in progress, the image isn't perfect, but it proves
that this works. Using the same code, it didn't work on my google map
basemap, same problem white map covering the basemap, but it worked on your
GrADS produced basemap. Can I ask you how you produced the basemap and
could you share your code to produce that basemap called
USNE.png?<BR><BR>Thanks again,<BR><BR><BR>Jeff<BR><BR><BR>
