I just thought I would include some code so you can see what I mean.
from mpl_toolkits.basemap import Basemap
import matplotlib.pyplot as plt
import numpy as np
map=Basemap(projection='aeqd', lat_0=46, lon_0=-118.4, width=28300000,
height=28300000,
resolution='c', area_thresh=1000.)
map.drawcoastlines()
map.drawcountries()
map.fillcontinents(color='coral')
map.drawmapboundary()
plt.show()
