title: How to create a reusable basemap
body: <p>In continuation to my previous question: <a href="https://stackoverflow.com/questions/31104867/how-to-superimpose-figures-in-matplotlib">How to superimpose figures in matplotlib</a> i would like to know how can one create a reusable <code>basemap</code> object.
  My problem is that a <code>basemap</code> is not a <code>pyplot</code> object, so the solution i received works well on <code>figures / axes</code> but not on <code>basemap</code> objects.</p>
  
  <p>I tried to look around and find a solution, but couldn't find any, just discussions.</p>
