Geocoding API 是一項服務，可接受地點為地址、經緯度座標或地點 ID。將地址轉換為經緯度座標和地點 ID，或將經緯度座標或地點 ID 轉換為地址。
使用 Geocoding API 的原因
如要在 Google 地圖平台 API 提供的地圖中使用地理編碼資料，請為網站或行動應用程式使用 Geocoding API。您可以使用 Geocoding API，將地址用於在地圖上放置標記，或將地圖上的標記轉換為地址。這項服務專門用於將預先定義的靜態地址進行地理編碼，以便將應用程式內容放置在地圖上。

Functionality varies by region. [Learn more](/maps/comms/eea/faq). \n\nThe Geocoding API is a service that accepts a place as an\naddress, latitude and longitude coordinates, or Place ID. It converts the\naddress into latitude and longitude coordinates and a Place ID, or converts\nlatitude and longitude coordinates or a Place ID into an address.\n| **Note** : If you only want plus codes and don't want to use an API key, you can use the [Plus codes API](https://github.com/google/open-location-code/tree/main/Documentation).\n\nWhy use the Geocoding API\n\nUse the Geocoding API for website or mobile application when you want to use\ngeocoding data within maps provided by one of the Google Maps Platform APIs.\nWith the Geocoding API, you use addresses to place markers on a map, or\nconvert a marker on a map to an address. This service is designed for geocoding\n**predefined, static addresses** for placement of application\ncontent on a map.\n| This service is **not** designed to respond directly to user\n| input. To do dynamic geocoding, for example, in a user interface, see the\n| [Maps JavaScript API\n| client geocoder](/maps/documentation/javascript/geocoding) and/or the\n| [Google Play services Location APIs](https://developer.android.com/google/play-services/location.html).\n\nWhat you can do with the Geocoding API\n\nYou can use the Geocoding API to obtain geocoding data for one or more addresses or\nplaces, including the following:\n\n- Geographic coordinates for addresses.\n- Addresses for sets of latitude and longitude coordinates.\n- Addresses for place IDs.\n\nYou can control where the results appear and constrain the results to a particular region,\ncounty, or postal code.\n\nHow the Geocoding API works\n\nThe Geocoding API does both geocoding and reverse geocoding:\n\n- [**Geocoding**](/maps/documentation/geocoding/requests-geocoding): Converts addresses such as \"1600 Amphitheatre Parkway, Mountain View, CA\" into latitude and longitude coordinates or Place IDs. You can use these coordinates to place markers on a map, or to center or reposition the map within the view frame.\n- [**Reverse geocoding**](/maps/documentation/geocoding/requests-reverse-geocoding): Converts latitude/longitude coordinates or a Place ID into a human-readable address. You can use addresses for a variety of scenarios, including deliveries or pickups.\n\nThe following demo uses the Geocoding Service through the Maps JavaScript API\nto demonstrate how the Geocoding API works. Open the map in a separate tab\nto see more options and details.\n\nResources\n\nThe following table summarizes the resources available through the\nGeocoding API along with the data each endpoint returns.\n\n| Data resources | Data returned | Return format |\n|-------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|---------------|\n| [Geocoding](/maps/documentation/geocoding/requests-geocoding) | Returns address, address components, and address types. See [Results](/maps/documentation/geocoding/requests-geocoding#results) in the *Geocoding request and response* guide. | - JSON - XML |\n| [Reverse geocoding](/maps/documentation/geocoding/requests-reverse-geocoding) | Returns address, address components, and address types. See [Reverse geocoding responses](/maps/documentation/geocoding/requests-reverse-geocoding#reverse-response) in the Reverse geocoding request and response guide. | - JSON - XML |\n| [Place geocoding](/maps/documentation/geocoding/requests-places-geocoding) | Returns address, address components, and address types. See [Reverse geocoding responses](/maps/documentation/geocoding/requests-places-geocoding) in the Place geocoding request and response guide. | - JSON - XML |\n| - JSON - XML |\n\nHow to use the Geocoding API\n\n|---|---------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| 1 | **Get set up.** | Start with [Set up your Google Cloud project](/maps/documentation/geocoding/cloud-setup) and complete the setup instructions that follow. |\n| 2 | **Try a geocoding request** | Once you have an API key, you can start testing out the Geocoding API directly from curl or a browser. You'll need to supply the correct lookup parameters for address or component lookups. See [Geocoding parameters](/maps/documentation/geocoding/requests-geocoding#geocoding-lookup) for details. |\n| 3 | **Try a reverse geocoding request** | Supply latitude/longitude coordinates along with your API key to obtain address components for the closest human-readable address for that location. See [Reverse geocoding requests](/maps/documentation/geocoding/requests-reverse-geocoding#reverse-requests) for details. |\n| 4 | **Understand response basics** | All endpoints in the Geocoding API return the same data in either JSON or XML. See [Geocoding responses](/maps/documentation/geocoding/requests-geocoding#GeocodingResponses) for an explanation of the data, status codes, and error messages. |\n| 5 | **Incorporate geocoding data into your own app!** | You can use geocoding data to obtain addresses from map markers or to supply markers on a map based on a known address. |\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- **Start using the Geocoding API** : Go to [Set up your\n Google Cloud project](/maps/documentation/geocoding/cloud-setup).\n- **Get started with sample requests and responses** : Go to [Geocoding requests and responses](/maps/documentation/geocoding/requests-geocoding)\n- **Follow best practices** : Go to [Geocoding Addresses Best\n Practices](/maps/documentation/geocoding/best-practices)."]]
