Mauro: I realized that this is actually possible with the Cassini projection (the transverse aspect of the cylindrical equidistant). from mpl_toolkits.basemap import Basemap import matplotlib.pyplot as plt width=20000000 m = Basemap(lon_0=0,lat_0=0,projection='cass',\ width=0.75*width,height=2*width) m.drawcoastlines() m.fillcontinents(color='coral',lake_color='aqua') m.drawparallels(range(-80,81,21)) m.drawmeridians(range(-180,181,60)) m.drawmapboundary(fill_color='aqua') plt.show() Don't know why you would actually do it though, if you want to show polar regions you should probably use the polar stereographic maps (npstere, spstere). -Jeff > With best regards, > > -- Jeffrey S.
