Kris,

For any sort of mapping like this, you will probably want to use basemap 
matplotlib toolkit, except that I don't see "hammer" among the supported 
projections.

With straight mpl, imshow does not support projections.  You could use 
pcolor (very slow) or pcolormesh.  In neither case will you get 
interpolation; you will be specifying colored quadrilaterals.
