Mauro: I just updated SVN basemap so you can specify just lon_0 for all cylindrical projections (cyl,gall,merc,mill) to get a global map centered on lon_0 (implying llcrnrlat=-90,urcrnrlat=90,llcrnrlon=lon_0-180,urcrnrlon=lon_0+180). > Using > this tip, I could also create a map centered on the Indian Ocean.
