[gradsusr] GrADS help, plotting shaded contour precip/ptype products over a basemap/background

Stephen,
I typically just use the standard grads background, however I am very
interested in how you create other base/background maps and use them. I
followed the previous email chain and was able to plot my data on
nwcoast.png, but now I'm curious how to create my own background images
from google maps.
Thanks,
Meredith

Jeff,
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
google basemap, if you didn't already attach earlier.

Hello Stephen,
Thanks for your code and sample 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?
Thanks again,
Jeff

Jeff,
Thanks for sending the image. I tried something very
similar using the same
colors, but only with precip. Resulting image attached,
along with the
short script to produce it. I also attached the
"USNE.png" background map
used.
One of the differences I see between your and my image
is that your
displayed (foreground) image borders appear to be
transparent while the
plotted white is not. My image sample appears to be
true in reverse, but I
don't know why. Perhaps my sample script will give you
a clue.
