L'API Geocoding est un service qui fournit le géocodage et le géocodage inversé des adresses.
Le geocoding consiste à convertir des adresses (comme une adresse postale) en coordonnées géographiques (comme la latitude et la longitude), que vous pouvez utiliser pour placer des repères sur une carte ou pour positionner celle-ci.
Le geocoding inversé consiste à convertir des coordonnées géographiques en adresses lisibles.
Vous pouvez également utiliser l'API Geocoding pour trouver l'adresse correspondant à un identifiant de lieu donné.
Exemple de requête et de réponse
Vous accédez à l'API Geocoding via une interface HTTP. Vous trouverez ci-dessous des exemples de requêtes de géocodage et de géocode inversé.
Requête de géocodage et réponse (recherche de latitude/longitude)
L'exemple suivant demande la latitude et la longitude de "1600 Amphitheatre Parkway, Mountain View, CA", et spécifie que la sortie doit être au format JSON.
Pour le tester, saisissez l'URL dans votre navigateur Web (assurez-vous de remplacer YOUR_API_KEY par votre clé API réelle).
La réponse inclut la latitude et la longitude de l'adresse.
Un exemple de réponse à une requête de géocodage est fourni ci-dessous, au format JSON :
{"results":[{"address_components":[{"long_name":"1600","short_name":"1600","types":["street_number"]},{"long_name":"Amphitheatre Parkway","short_name":"Amphitheatre Pkwy","types":["route"]},{"long_name":"Mountain View","short_name":"Mountain View","types":["locality","political"]},{"long_name":"Santa Clara County","short_name":"Santa Clara County","types":["administrative_area_level_2","political"]},{"long_name":"California","short_name":"CA","types":["administrative_area_level_1","political"]},{"long_name":"United States","short_name":"US","types":["country","political"]},{"long_name":"94043","short_name":"94043","types":["postal_code"]}],"formatted_address":"1600 Amphitheatre Pkwy, Mountain View, CA 94043, USA","geometry":{"location":{"lat":37.4267861,"lng":-122.0806032},"location_type":"ROOFTOP","viewport":{"northeast":{"lat":37.4281350802915,"lng":-122.0792542197085},"southwest":{"lat":37.4254371197085,"lng":-122.0819521802915}}},"place_id":"ChIJtYuu0V25j4ARwu5e4wwRYgE","plus_code":{"compound_code":"CWC8+R3 Mountain View, California, United States","global_code":"849VCWC8+R3"},"types":["street_address"]}],"status":"OK"}
Requête de géocodage inversé et réponse (recherche d'une adresse)
L'exemple suivant demande l'adresse correspondant à une latitude/longitude donnée à Brooklyn (New York, États-Unis). Il indique également que la réponse doit être au format JSON.
Pour le tester, saisissez l'URL dans votre navigateur Web (assurez-vous de remplacer "YOUR_API_KEY" par votre clé API réelle).
La réponse inclut une adresse lisible par l'humain pour la latitude et la longitude.

Functionality varies by region. [Learn more](/maps/comms/eea/faq).\n| **Before you begin:** Before you start using the Geocoding API, you need a project with a billing account and the Geocoding API enabled. We recommend creating multiple Project Owners and Billing Administrators, so that you'll always have someone with these roles available to your team. To learn more, see [Set up in Cloud console](/maps/documentation/geocoding/cloud-setup).\n\nThe Geocoding API is a service that provides geocoding and reverse geocoding\nof addresses.\n| This service is also available as part of the client-side [Google Maps JavaScript\n| API](/maps/documentation/javascript/geocoding), or for server-side use with the [Java Client,\n| Python Client, Go Client and Node.js Client for Google Maps Services](/maps/documentation/geocoding/client-library).\n\n**Geocoding** is the process of converting addresses (like a street address)\ninto geographic coordinates (like latitude and longitude), which you can use to place markers\non a map, or position the map.\n\n**Reverse geocoding** is the process of converting geographic coordinates\ninto a human-readable address.\n\nYou can also use the Geocoding API to find the address for a\ngiven [place ID](/maps/documentation/geocoding/requests-places-geocoding).\n\nSample request and response\n\nYou access the Geocoding API through an HTTP interface.
