I need to display another contour for the continents for the LGM time
and to show the prognostic variables over this new background. I know
don't display the GRADS default contour map for the actual continents
(set mpdraw off) but I don't know how to get display a new
contour as a backgournd. I have as output from my model the new land
contour in the binary file format. Is possible superpose both images?
That means: to superpose the image of my prognostic variable (e. g.
Precipitation) over the LGM contour of the continents?<br>
How to do that?<br>
I will be very gratefull if someone can help me.</font></div></div></blockquote><div><br></div><div>The Shapefile extension</div><div><br></div><div><p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica"> <a href="http://opengrads.org/doc/udxt/shape/">http://opengrads.org/doc/udxt/shape/</a></p>
</div></div><div><br></div><div>allows you to display continent outlines available as shapefiles. I am not sure what you mean by "LGM contour of the continents" but if this is available as a shapefile, you can could do something like</div>
