Greetings,
I have global data that I would like to plot using mpl_toolkits.basemap. The catch is that I want to mask out all data over the ocean. I know there is a function to fill continents,map.fillcontinents(), but I can’t seem to find one for filling oceans. Ideally, I want the oceans to show up with a white background and no data contoured.
Am I completely missing something or is this functionality missing?
Thanks,
···

Patrick: There is a drawlsmask method that can fill ocean and land pixels different colors. See http://matplotlib.sourceforge.net/basemap/doc/html/api/basemap_api.html for details. You can make the land transparent, and the ocean white for example. It's based on a 5 minute land/sea mask dataset, although you can use your own (as long as it's global and defined on a regular lat/lon grid).
