Mike: Note that you don't actually need to recreate the basemap instance each time through the loop (since the map projection region is not changing). AFAIK there are no serious memory leaks in basemap with python 2.5 - so if you can provide an example that triggers one I'd like to see it. Sounds like it might only be occurring with python 2.6? -Jeff -- Jeffrey S.
