 ## Comments
-This submission fixes a bug in the get_elev_raster function.  The response type changed on the API side and internal checks were failing.  This is corrected.  Also, three packages were listed as Imports, but not called.  That has been fixed and all NOTES listed in the CRAN checks should be addressed.

Lastly, a deprecation notice for the mapzen api (which is shutting down soon) was added.
