I often produce images for use in .KML with Google Earth. Sometimes I need the masking effect of matplotlib.toolkits.basemap.Basemap.fillcontinents but in the case of Google Earth, I need to make continents transparent on the final image. Any ideas on how to do this?
Have you tried setting the color argument in fillcontinents() with a RGBA tuple? Even if that doesn't work, you still have a list of matplotlib.patches.Polygon objects being returned by the function. You could then call set_alpha() on each of them to a transparency value of choice.
I hope that helps!
