[Matplotlib-users] Continent Transparency

All, 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? Thanks! Bruce --

Does anyone have an example of nested grids. I need to (for instance), plot a global grid in filled contours, then plot another, higher resolution grid over the US. The global grid could work something like this, but I'm not sure where to start with the 2nd (nested) grid to go atop. fig=plt.figur
