A API Geolocation é um serviço que aceita uma solicitação HTTPS com a torre de celular e os pontos de acesso Wi-Fi que um cliente móvel pode detectar. Ele retorna coordenadas de latitude/longitude e um raio que indica a precisão do resultado para cada entrada válida.
Por que usar a API Geolocation
Use a API Geolocation para localizar dispositivos móveis que não oferecem recursos nativos de geolocalização.
O que você pode fazer com a API Geolocation
Com a API Geolocation, é possível usar dados geoespaciais de torres de celular e nós de Wi-Fi para encontrar a localização de um dispositivo sem geolocalização nativa ou GPS.
Como a API Geolocation funciona
A API Geolocation usa campos de dados de dispositivos móveis, dados de torres de celular e dados de matriz de pontos de acesso Wi-Fi para retornar coordenadas de latitude/longitude e um raio de precisão. Ele aceita uma solicitação POST HTTPS para o endpoint com um corpo de solicitação estruturado em JSON. O exemplo a seguir mostra o URL da solicitação e um exemplo de corpo da solicitação:
A API pode retornar dados para vários campos comuns de dados de celular, conforme indicado abaixo.
Recursos
A tabela a seguir resume os campos no corpo da solicitação da chamada do endpoint de geolocalização, além do tipo de dados fornecidos por essas consultas.
Depois de ter uma chave de API, você pode começar a testar a API Geolocation usando cURL ou
Postman. Consulte Exemplos de solicitações no guia Solicitações e respostas de geolocalização para mais detalhes.
Analise as respostas de dados de geolocalização para se preparar para usar dados de elevação no seu app. Consulte

For more information, go to [Geolocation:\n| Displaying User or Device Position on Maps](/maps/documentation/javascript/geolocation).\n| - **Mobile devices geolocation** : Go to [Geocoding API](/maps/documentation/geocoding/overview).\n|\n| For more information on the W3C Geolocation standard, see\n| [W3C Geolocation standard](https://w3c.github.io/geolocation-api/).\n\nWhat you can do with the Geolocation API\n\nWith the Geolocation API, you can use geospatial data from cell towers\nand WiFi nodes to get the location of a device that does not have native geolocation or GPS.\n\nHow the Geolocation API works\n\nThe Geolocation API uses cellular device data fields, cell tower\ndata, and WiFi access point array data to return latitude/longitude coordinates and an accuracy\nradius. It accepts an HTTPS POST request to its endpoint along with a JSON structured request\nbody. The following example shows the request URL and an example request body:\n\n```json\ncurl -X POST \"https://www.googleapis.com/geolocation/v1/geolocate?key=\u003cvar translate=\"no\"\u003eYOUR_API_KEY\u003c/var\u003e\" \\\n-H \"Content-Type: application/json\" \\\n-d \\\n'{ \"homeMobileCountryCode\":310,\n \"homeMobileNetworkCode\":410,\n \"radioType\":\"gsm\",\n \"carrier\":\"Vodafone\",\n \"considerIp\":true\n}'\n```\nThe API can return data for a number of common cellular data fields as indicated below.\n\nResources\n\nThe following table summarizes the fields in the request body of the geolocation endpoint\ncall, along with the type of data provided from such queries.\n\n| Data resources | Data returned | Return format |\n|----------------------------------------------------------------------------------------------------------------------------------------------------|-------------------------------------------------------|---------------|\n| [Cell device data fields](/maps/documentation/geolocation/requests-geolocation#body) such as carrier, device, and network information. | Latitude/longitude coordinates and an accuracy radius | JSON |\n| [Cell tower data](/maps/documentation/geolocation/requests-geolocation#cell_tower_object), such as location area code and mobile country codes. | Latitude/longitude coordinates and an accuracy radius | JSON |\n| [WiFi access points data](/maps/documentation/geolocation/requests-geolocation#wifi_access_point_object), such as MAC address and signal strength. | Latitude/longitude coordinates and an accuracy radius | JSON |\n\nHow to use the Geolocation API\n\n|---|------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| 1 | **Get set up** | Start with [Set up your Google Cloud project](/maps/documentation/elevation/cloud-setup) and complete the setup instructions that follow. |\n| 2 | **Try a geolocation request** | Once you have an API key, you can start testing out the Geolocation API using cURL or Postman.
