Handling KML/CSV with geopandas - DriverError: unsupported driver: u'CSV'

in case of csv, it probably would be easier to read it with pandas and then convert it to geopandas Dataframe

import pandas as pd
import geopandas as gp
from shapely.geometry import Point

stations = pd.read_csv('../data/stations.csv')
stations['geometry'] = stations.apply(lambda z: Point(z.X, z.Y), axis=1)
stations = gp.GeoDataFrame(stations)

The KML driver isn't enabled by default as detailed in this github issue https://github.com/Toblerity/Fiona/issues/97. Basically, the KML driver doesn't seem to meet Fiona's quality requirements (as of 2014), not sure if it will be fixed in the future.

You could try to read a simple/standard-enough KML as follows:

import geopandas as gpd
fiona.drvsupport.supported_drivers['kml'] = 'rw' # enable KML support which is disabled by default
fiona.drvsupport.supported_drivers['KML'] = 'rw' # enable KML support which is disabled by default

gpd.read_file("/path/to/your/test.kml")

I've tried to read a file here and it gave me the following output:

Edit 20191021: With newer versions of fiona, you might need to use libkml instead of kml. I.e.:

fiona.drvsupport.supported_drivers['libkml'] = 'rw' # enable KML support which is disabled by default
fiona.drvsupport.supported_drivers['LIBKML'] = 'rw' # enable KML support which is disabled by default

GeoPandas relies on the Fiona library (http://github.com/toblerity/Fiona) for the from_file() implementation. At this time Fiona, and therefore GeoPandas, does not support CSV or KML input. If you can convert them to GeoJSON or Shapefiles, then GeoPandas should be able to read without a problem.
