The built-in country dataset in Basemap is made up of line segments, so you can't fill them. Here's a simple example to get you started:
import numpy as np import matplotlib.pyplot as plt from mpl_toolkits.basemap import Basemap as Basemap from matplotlib.patches import Polygon # Robinson world map m = Basemap(projection='robin',lon_0=0) # draw country boundaries # data from http://www.cipotato.org/diva/data/misc/world_adm0.zip shp_info = m.readshapefile('world_adm0','countries',drawbounds=True) ax = plt.gca() # get current axes instance # fill US blue, Russia red, the rest gray. for nshape,seg in enumerate(m.countries): if m.countries_info[nshape]['NAME'] == 'United States': poly = Polygon(seg,facecolor='b',edgecolor='b') elif m.countries_info[nshape]['NAME'] == 'Russia': poly = Polygon(seg,facecolor='r',edgecolor='r') else: poly = Polygon(seg,facecolor='0.7',edgecolor='0.7') ax.add_patch(poly) # draw meridians and parallels. m.drawparallels(np.arange(-80,81,20)) m.drawmeridians(np.arange(-180,180,60)) # draw projection limb, set background color m.drawmapboundary(fill_color='aqua') plt.title('US Blue, Russia Red') plt.show() -Jeff -- Jeffrey S.
