Nice! As for your error, I took a quick look at your script. If you use Basemap, you should draw the coastlines on the map object, m. Not the axis object, ax. m.drawcoatlines() Sent from Mail for Windows 10 From: Ryan Connelly Sent: Tuesday, April 25, 2017 4:39 PM To: Brian Blaylock Cc: python-users@xxxxxxxxxxxxxxxx Subject: Re: [python-users] MetPy NEXRAD Level 2 - Can get lat, lon out to usefor plotting map? Hi Kevin and Brian, I used Brian's script, which successfully georeferences the radar data. But I'm still not getting my Cartopy features to show up. I would just use Basemap, except that that throws an error: AttributeError: 'GeoAxesSubplot' object has no attribute 'drawcoastlines'. I've attached my modified version of the code, as well as an example plot.

I did what he suggested (using pyproj to convert the range and azimuth to a latitude longitude).
