Elevation API를 사용하여 고도를 지원하는 애플리케이션을 개발할 수 있습니다.
고도에 민감한 활동, 포지셔닝 애플리케이션 또는 낮은 조사를 이용 중인 고객
경로에 있는 고도 및 고도 변화를 포함하는 애플리케이션입니다. 예를 들어
고도 상승 및 손실 데이터를 제공하여
하이킹, 자전거 또는 스쿠버 다이빙과 같은 활동을 할 수 있습니다.
Elevation API로 할 수 있는 작업
Elevation API를 사용하면 고도 데이터를
지도에 표시할 수 있습니다. 예를 들면 다음과 같습니다.
특정 장소의 고도 확인
특정 경로 또는 둘 사이의 고도 차이를 계산합니다.

Elevation API 작동 방식
Elevation API는 요청을 위도/경도 좌표가 있는 인코딩된 URL로 수락합니다.
개별 위치 또는 경로를 따라 일련의 위치로 제공됩니다. 이 요청은
예를 들어 콜로라도주 덴버의 중심에 대한 고도를 쿼리하고 반환을 JSON 형식으로 지정합니다.
Google 지도용 Java 클라이언트, Python 클라이언트, Go 클라이언트, Node.js 클라이언트
서비스는 커뮤니티 지원 클라이언트 라이브러리로,
Apache 2.0 라이선스.

For example,\nyou can provide elevation gain and loss data to enhance a sports application for activities such\nas hiking, biking, or scuba diving.\n\nWhat you can do with the Elevation API\n\nWith the Elevation API, you can include elevation data in your\napplications or on a map. For example:\n\n- Get the **elevation** for a particular place.\n- Calculate the **differences** in elevation along a route or between two points.\n\nHow the Elevation API works The Elevation API accepts a request as an encoded URL with latitude/longitude coordinates provided as either discrete locations, or as a series of locations along a path. This request, for example, queries elevation for the center of Denver, Colorado, specifying a return in JSON format. \n\n```scdoc\n https://maps.googleapis.com/maps/api/elevation/json\n ?locations=39.7391536%2C-104.9847034\n &key=YOUR_API_KEY\n```\n\nThe service derives the elevation for the provided coordinates. It also interpolates\nelevation for a location without elevation, providing an average returned from the four\nnearest locations that do provide elevation data. Finally, it determines the overall\nresolution for the location.\n\nResources\n\nThe following table summarizes the resources available through the\nElevation API along with the data it returns.\n\n| Data resources | Data returned | Return format |\n|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|---------------|\n| **Latitude/longitude coordinates** You can provide data as a set of one or more locations, or as a series along a path. You can also provide encoded coordinates. Pass up to 512 coordinates. | The Elevation API provides **elevation in meters** relative to the **local mean sea level** (LMSL). Elevation can be returned as positive or negative values as indicated below: - **Positive values** indicate locations above LMSL, including surface locations or the bottom of high-altitude lakes. - **Negative values** indicate locations that are below LMSL, including locations on the surface or the ocean floor. - **Resolution** indicates the distance between the data point and the elevation, in meters. | - JSON - XML |\n\nHow to use the Elevation 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 an elevation request** | Once you have an API key, you can start testing out the Elevation API directly from your browser. See [Sample requests](/maps/documentation/elevation/start#sample-request) in the *Getting started* guide for details. |\n| 3 | **Compose a more complex request** | Once you are set up with a project, try a request that supplies a location data along a path. See [Specifying paths](/maps/documentation/elevation/requests-elevation#Paths) for details. |\n| 4 | **Understand response basics** | Explore the elevation data responses to prepare to use elevation data for your app. See [Elevation responses](/maps/documentation/elevation/requests-elevation#ElevationResponses) for details. |\n| 5 | **Incorporate elevation data into your own app!** | You can use elevation data to enhance location-based apps, such as apps for sports activities or for survey data. |\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 Elevation API** : Go to [Set up your\n Google Cloud project](/maps/documentation/elevation/cloud-setup).\n- **Try getting path-based elevation data** : Go to [Specifying paths](/maps/documentation/elevation/requests-elevation#Paths)\n- **Follow best practices** : Go to [Web Service\n Best Practices](/maps/documentation/elevation/web-service-best-practices)."]]
