Map-Immo / python geocoder with BANO

Toutes les agences immobilières parisiennes de SeLoger.com geocodées via BANO

Données consultables ici : https://github.com/RouxRC/map-immo/blob/master/agences.tsv Et visualisées grâce à uMap ici : https://umap.openstreetmap.fr/fr/map/map-immo-paris_16133

Ce code est publié sous licence GPL v3 et les données sous licence ODBL. Elles ont été scrappées sur SeLoger.com et géolocalisées grâce à Bano d'OpenStreetMap France.

Le geocoder python employé est réutilisable en utilisant simplement le fichier geocode.py sans rien de plus. les données bano requises sont téléchargées à la volées et cachées dans un dossier .cache.

Par exemple :

# import the GeoCoder class
from geocode import GeoCoder

# instantiate it
G = GeoCoder()
# optionnally make it verbose on errors
G = GeoCoder(verbose=True)

# geocode an adress
G.geocode("16, rue Pierre Lescot 75001 Paris")
> (48.86219, 2.348475)
# optionnally get fixed postcode returned
# note it will try and fix possible wrong postcodes by looking through others
G.geocode("16 r Pierre Lescot 75003 Paris", return_postcode=True)
> (75001, 48.86219, 2.348475)

# provide preknown postcode
G.geocode("16 Pierre Lescot", 75001)
> (48.86219, 2.348475)
# provide preknown details with lower level find_street function
# note the handling of street types such as rue, blvd, etc. is handled blurily
G.find_street(75001, "reu Pierre Lescot", 16)
> (48.86219, 2.348475)
# although providing wrong street names won't be handled automatically
# the result on mismatch will be None instead of a tuple
# and in verbose mode an error will be displayed in stderr
G.geocode("16 r Piere Lescot 75003 Paris", return_postcode=True)
> [ERROR] Could not find a street "ruepierelescot" with postcode 75003 in bano data
> 

# adresses with no number will return coordinates for the middle of the street
G.geocode("Pierre Lescot", 75001)
> (48.863034, 2.34866)
# adress with number missing from Bano data will return coordinates from the 
# closest existing number, priorily on the same side of the street
G.geocode("160 Pierre Lescot 75001")
> (48.864977, 2.330415)
