Geolocation API는 모바일 클라이언트가 감지할 수 있는 휴대폰 기지국 및 Wi-Fi 액세스 포인트가 포함된 HTTPS 요청을 수락하는 서비스입니다. 유효한 각 입력에 대해 위도/경도 좌표와 결과의 정확도를 나타내는 반경을 반환합니다.
Geolocation API를 사용하는 이유
Geolocation API를 사용하여 기본 위치정보 기능을 제공하지 않는 모바일 기기를 찾습니다.
Geolocation API로 할 수 있는 작업
Geolocation API를 사용하면 휴대폰 기지국 및 Wi-Fi 노드의 지리 공간 데이터를 사용하여 기본 위치 정보나 GPS가 없는 기기의 위치를 파악할 수 있습니다.
Geolocation API 작동 방식
Geolocation API는 셀룰러 기기 데이터 필드, 휴대폰 기지국 데이터, Wi-Fi 액세스 포인트 배열 데이터를 사용하여 위도/경도 좌표와 정확도 반경을 반환합니다. JSON 구조화된 요청 본문과 함께 엔드포인트에 대한 HTTPS POST 요청을 수락합니다. 다음 예시에서는 요청 URL과 요청 본문의 예를 보여줍니다.
Google 지도 서비스용 Java Client, Python Client, Go Client, Node.js Client는 커뮤니티 지원 클라이언트 라이브러리로, Apache 2.0 라이선스에 따라 오픈 소스로 제공됩니다.

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. See [Sample requests](/maps/documentation/geolocation/requests-geolocation#sample-requests) in the Geolocation requests and response guide for details. |\n| 3 | **Get the cellID from different radio towers** | See [Calculating cellID](/maps/documentation/geolocation/requests-geolocation#calculating_cell_id) and [Calculating newRadioCellID](/maps/documentation/geolocation/requests-geolocation#sample-requests) to get access to older and newer towers, respectively. |\n| 4 | **Understand response basics** | Explore the geolocation data responses to prepare to use elevation data for your app. See [Geolocation responses](/maps/documentation/geolocation/requests-geolocation#responses) for details. |\n\nAvailable client libraries\n\nCall this API in the language of\nyour choice through one of the following client libraries:\n\n- [Java\n Client for Google Maps Services](https://github.com/googlemaps/google-maps-services-java)\n- [Python\n Client for Google Maps Services](https://github.com/googlemaps/google-maps-services-python)\n- [Go Client\n for Google Maps Services](https://github.com/googlemaps/google-maps-services-go)\n- [Node.js\n Client for Google Maps Services](https://github.com/googlemaps/google-maps-services-js)\n\nThe Java Client, Python Client, Go Client and Node.js Client for Google Maps\nServices are community-supported client libraries, open sourced under the\n[Apache 2.0 License](http://www.apache.org/licenses/LICENSE-2.0).\nDownload them from GitHub, where you can also find installation instructions and sample code.\n\nWhat's next\n\n- **Get started with sample requests and responses** : Go to [Geolocation request and response](/maps/documentation/geolocation/requests-geolocation)\n- **Follow best practices** : Go to [Web Service Best Practices](/maps/documentation/geolocation/web-service-best-practices).\n- **Understand billing** : Go to [Usage and Billing](/maps/documentation/geolocation/usage-and-billing)."]]
