This relates to the question here: Reading data to geopandas using WFS?

Is there a way to to do the same with a service that does not supply the data in GeoJSON format, but in GML-format?

The webservice is: https://arealinformation.miljoeportal.dk/gis/services/DAIdb/MapServer/WFSServer

And I want to read a single layer.

import geopandas as gp
import requests
from fiona import BytesCollection    

def wfs2gp_df(layer_name, url, bbox=None, wfs_version="2.0.0", outputFormat='application/gml+xml; version=3.2'):
    params = dict(service='WFS', version=wfs_version,request='GetFeature', typeName=layer_name, outputFormat=outputFormat)
    with BytesCollection(requests.get(url,params=params).content) as f:
        df = gp.GeoDataFrame.from_features(f)
    return df

wfs2gp_df('your_wfs_layer_name', 'your_wfs_url').head()

  • Using outputFormat=json did the trick for me. For some reason I failed to import XML/GML into GeoPandas. Jan 14, 2022 at 11:35
  • It is not guaranteed that the WFS server offers the json format

  • yes, that's correct. However, the server I'm working with can do that and I got results with JSON output. Obviously it would be great if XML/GML would work in my project. Jan 16, 2022 at 10:33
