[python #XFQ-820961]: Level-III to geojson

Greetings!

MetPy has a function for converting azimuth and ranges around a center point 
(i.e. a radar) to lat/lons by using great circle distances. You should be able 
to use that to get the lat/lons you need for geojson.

  
https://unidata.github.io/MetPy/latest/api/generated/metpy.calc.azimuth_range_to_lat_lon.html#metpy.calc.azimuth_range_to_lat_lon

This example uses that to plot on a map using lat/lons:

  
https://unidata.github.io/MetPy/latest/examples/formats/NEXRAD_Level_3_File.html#sphx-glr-examples-formats-nexrad-level-3-file-py

I'm not familiar at all about the writing/formatting of geojson, so I'm not 
sure what tool to turn to for that. Fiona? Geopandas? 

Hope this helps!

Ryan
