Hello,
I could easily be doing something wrong. I posted this issue about two
years ago and never saw a response, so I'll try again. It's more of an
academic question - I can work around the issue. In the following code, I'm
trying to plot a regional ortho projection over central Europe (I've
commented out the global projection), and then trying to use a bluemarble
background. As you can see from the attached image, global bluemarble
background is plotted, not a regional one. This also happens with
shadedrelief and etopo.

import mpl_toolkits.basemap as bm
import matplotlib.pyplot as plt
import numpy as np
"""
theMap = bm.Basemap(projection='ortho',
lat_0=48.2, lon_0=16.4)
"""
theMap = bm.Basemap(projection='ortho',
lat_0=48.2, lon_0=16.4,
llcrnry=-1000000.0, llcrnrx=-1000000.0,
urcrnry=1000000.0, urcrnrx=1000000.0,

theMap.drawcoastlines()
theMap.bluemarble()
plt.show()

Indeed, that is obviously wrong. Could you file a bug report up on
basemap's github page? Basemap is now under new management, so I will see
what I can do to address the problem for you.
Cheers!
