[TriPython] Setting a 10m buffer on a point in Geopandas

[Ryan Cooper]

Greg-

As I was looking closer at your notebook and the error message you sent it
occurred to me that perhaps the original CRS, EPSG:4326, was not set on the
geometry series of your GeoDataFrame. As such there would be no way to
transform your data from EPSG:4326 to EPSG:3395. See notebook here for a
possible solution to your issue.
