Lors de la recherche d'une ville sur Google Maps, les limites administratives de la ville sont affichées.
Existe-t-il un moyen d’obtenir les limites des polygones de City au format JSON à l’aide de Google Maps api?

Réponses:
Vous pouvez obtenir des coordonnées de polygones dans json pour pouvoir les utiliser avec googlemaps avec openstreetmap. Allez à http://nominatim.openstreetmap.org/ recherchez un lieu comme "Partido de Ituzaingó"
cliquez sur "détails"
Recherchez l'ID OSM et copiez-le (contrôle + c), exemple: 2018776
collez l'ID dans http://polygons.openstreetmap.fr/index.py et téléchargez le polygone
5638803
, Je lance global.mapit.mysociety.org/code/osm_rel/5638803 Je reçois{"code": 404, "error": "No areas were found that matched code osm_rel = 5638803."}
Pour obtenir des limites de polygones, ajoutez simplement format=json
à votre demande!
Donc, au lieu de https://nominatim.openstreetmap.org/search.php?q=Warsaw+Poland&polygon_geojson=1
utilisation
https://nominatim.openstreetmap.org/search.php?q=Warsaw+Poland&polygon_geojson=1&format=json
En ajoutant & format = geojson, vous pouvez obtenir une réponse geojson valide.
Non, il n'y a aucun moyen de voler les données de Google. Peut-être que vous pourriez regarder OpenStreetMap qui est conçu pour être téléchargé.
J'ai trouvé une solution de contournement pour résoudre ce problème.
Vous pouvez utiliser lat, long data et les analyser dans un tableau. Cette solution fonctionne bien, mais la qualité du parcours est parfois rugueuse.
En guise d'alternative à l'API Google Maps, OpenStreetMap peut vous aider à rechercher une ville par son nom dans cette page http://nominatim.openstreetmap.org/ . Consultez ensuite les résultats de la recherche et vous pouvez obtenir les coordonnées de région au format GeoJSON, par exemple ( http://nominatim.openstreetmap.org/details.php?place_id=145126778 ) pour obtenir les coordonnées de mashhad geojson dans l'onglet Administration.
Obtenez des coordonnées exactes comme la recherche Google au format JSON.
