Elevation API adalah layanan yang mengembalikan data elevasi untuk
sebuah lokasi di atas bumi, atau mengambil sampel data elevasi sepanjang jalur.
Alasan menggunakan Elevation API
Dengan Elevation API, Anda dapat mengembangkan aplikasi untuk mendukung
pelanggan dengan aktivitas yang sensitif terhadap ketinggian, aplikasi pemosisian, atau survei rendah
yang mencakup perubahan elevasi dan elevasi di sepanjang rute. Misalnya,
Anda bisa memberikan data peningkatan dan penurunan ketinggian untuk meningkatkan aplikasi olahraga untuk aktivitas seperti
seperti hiking, bersepeda, atau selam skuba.
Yang dapat Anda lakukan dengan Elevation API
Dengan Elevation API, Anda dapat menyertakan data elevasi dalam
aplikasi atau pada peta. Contoh:
Dapatkan ketinggian untuk tempat tertentu.
Hitung perbedaan ketinggian di sepanjang rute atau antara dua
poin.
Cara kerja Elevation API
Elevation API menerima permintaan sebagai URL yang dienkode dengan koordinat lintang/bujur
sebagai lokasi terpisah, atau sebagai serangkaian lokasi di sepanjang jalur. Permintaan ini,
misalnya, elevasi kueri untuk pusat Denver, Colorado, dengan menentukan return dalam format JSON.
Layanan memperoleh elevasi untuk koordinat yang diberikan. Pola ini juga berinterpolasi
elevasi untuk lokasi tanpa elevasi, yang memberikan data rata-rata yang ditampilkan
lokasi terdekat yang menyediakan data elevasi. Akhirnya, hal ini menentukan keseluruhan
resolusi untuk lokasi tersebut.

Format pengembalian
Koordinat lintang/bujur
Anda dapat memberikan data sebagai kumpulan dari satu atau beberapa lokasi, atau sebagai deret di sepanjang jalur. Anda
juga dapat memberikan koordinat yang dienkode. Teruskan hingga 512 koordinat.
Elevation API memberikan ketinggian dalam meter relatif
dengan permukaan laut rata-rata lokal (LMSL). Elevasi dapat ditampilkan sebagai positif
atau negatif seperti yang ditunjukkan di bawah ini:
Nilai positif menunjukkan lokasi di atas LMSL,
termasuk lokasi permukaan atau dasar danau dataran tinggi.
Nilai negatif menunjukkan lokasi yang berada di bawah LMSL, termasuk
lokasi di permukaan atau dasar samudra.
Resolusi menunjukkan jarak antara titik data dan
elevasi, dalam meter.
Setelah memiliki kunci API, Anda dapat mulai menguji Elevation API secara langsung dari
browser Anda. Lihat Contoh permintaan
dalam panduan Memulai untuk mengetahui detailnya.

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)."]]
