It's same problem for which I asked assistance here:
http://www.mail-archive.com/matplotlib-users@lists.sourceforge.net/msg22520.html
There, Johann provided nifty script with slider, with which help user
can shift colormap and get more "meaningful" image
Also speaking about great Basemap package,
I just came across this paper in my twitter feed. Thought it might be relevant
to this community.
