Python and Basemap and remove Mexico / Canada from view

Question

I use the Basemap in Matplotlib to draw a map of the United States. However, I seem to be unable to remove Mexico or Canada to show the USA. I need to also draw states. My current code is:

self.map = Basemap(llcrnrlon=-119, llcrnrlat=22, urcrnrlon=-64, urcrnrlat=49, projection='lcc', lat_1=33, lat_2=45, lon_0=-95, resolution='i', area_thresh=10000,ax=self.axes) self.map.drawcoastlines() self.map.drawcountries() self.map.drawstates() self.figure.canvas.draw() 

It attracts the USA with some Mexico and Canada. If I comment on self.map.drawcountries() , the southern and northern borders of the United States will be removed, so this will not help. If I comment on self.map.drawcoastlines() , this will remove the borders of East and West. I can’t find any other team that allows me to have only the USA (with states).

Any ideas? Thanks!

You need to draw the polygons yourself. This can be done by reading the shapefile. See the fillstates.py example for US states (without Mexico or Canada).
