Explorer un provider avec l'API carto (en version beta sur les flux du géoportail)
Pas réussi à attaquer directement les flux WFS (retour systématique d'un "MissingParameter" non précisé).
Ne fonctionne pas :
from owslib.wfs import WebFeatureService
url = "https://wxs.ign.fr/geoportail/wfs"
wfs = WebFeatureService(url=url, version='2.0.0')
cog_files = [
x for x in wfs.contents
if 'cog' in x.lower()
and 'carto' in x.lower()
and 'latest' in x.lower()
]
print(wfs.getfeature(cog_files[-1]).read())
En revanche, l'appel via l'API carto en version beta fonctionne ; le débit semble beaucoup plus rapide que sur le site de l'IGN (mais les md5 ne sont par contre pas fournis, il faudra les calculer à réception) :
from owslib.wfs import WebFeatureService
import geopandas as gpd
import requests
url = "https://wxs.ign.fr/geoportail/wfs"
wfs = WebFeatureService(url=url, version='2.0.0')
cog_files = [
x for x in wfs.contents
if 'cog' in x.lower()
and 'carto' in x.lower()
and 'latest' in x.lower()
]
print(cog_files)
file = cog_files[-1]
bbox_world = """{"type":"Polygon", "coordinates":[[[-180,-90],[-180,90],[180,90],[180,-90],[-180,-90]]]}"""
r = requests.get(
'https://apicarto.ign.fr/api/wfs-geoportail/search',
params={"source":file, "geom":bbox_world}
)
gdf = gpd.GeoDataFrame.from_features(r.json())
gdf.plot()
Poursuite des tests : résultats de l'API plafonnés par sections de 1000 entités, ce qui ralentit l'opération.
Code complet avec boucle :
bbox_world = """{"type":"Polygon", "coordinates":[[[-180,-90],[-180,90],[180,90],[180,-90],[-180,-90]]]}"""
r = requests.get(
'https://apicarto.ign.fr/api/wfs-geoportail/search',
params={"source":"ADMINEXPRESS-COG-CARTO.LATEST:commune", "geom":bbox_world},
stream=True
)
data = []
while True:
chunk = r.json()
data.append(gpd.GeoDataFrame.from_features(chunk))
try:
link = [x for x in chunk["links"] if x['rel'] == "next"][0]['href']
except Exception:
break
r = requests.get(link, stream=True)
gdf = gpd.pd.concat(data)
Résultats :
print(gdf.shape)
