<h1>Free Elevation API Service</h1>
|

<p>Get the elevation of every point on Earth.</p>
|

</header>
|

<section>
|
||||
<h2>About This Service</h2>
|
||||
<p>This API provides you with access to elevation data across Earth's globe, absolutely free of charge.</p>
|
||||
</section>
|
||||
<section>
|
||||
<h2>API Usage</h2>
|
||||
<p>To use the API, make a GET request to this endpoint with the required parameters. Here is an example request:
|
||||
</p>
|
||||
<code>https://www.elevation-api.eu/v1/elevation/:lat/:lon[?json]</code>
|
||||
<h3>Parameters:</h3>
|
||||
<ul>
|
||||
<li><strong>lat</strong> - Latitude of the location, WGS-84</li>
|
||||
<li><strong>lon</strong> - Longitude of the location, WGS-84</li>
|
||||
<li><strong>?json</strong> - Append this to have the result retuned as JSON</li>
|
||||
</ul>
|
||||
<h3>Response:</h3>
|
||||
<p>The API will return the elevation in meters. For example:</p>
|
||||
<code>42</code>
|
||||
<p>If the point is not into the DEM dataset, the response code will be 501 (or <code>Null</code> in JSON mode)
|
||||
</p>
|
||||
<h3>Try it out:</h3>
|
||||
<a href="http://www.elevation-api.eu/v1/elevation/46.24566/6.17081">Get the elevation of the Lake Leman</a>
|
||||
</section>
|
||||
<section>
|
||||
<h2>JSON API endpoint (multi coordinates)</h2>
|
||||
You can also request many coordinates at once by using the following endpoint:
|
||||
<code>https://www.elevation-api.eu/v1/elevation?pts=[[lat1,lon1],[lat2,lon2],[lat3,lon3]]</code>
|
||||
<h4>Example</h4>
|
||||
<code><a href="https://www.elevation-api.eu/v1/elevation?pts=[[46.24566,6.17081],[46.85499,6.78134]]">
|
||||
https://www.elevation-api.eu/v1/elevation?pts=[[46.24566,6.17081],[46.85499,6.78134]]
|
||||
</a></code>
|
||||

|
||||
<h2>Misc</h2>
|
||||
<h3>Data source</h3>
|
||||
<p>The digital elevation data comes from ESA's Copernicus program.</p>
|
||||
<h3>Rate limits</h3>
|
||||
<p>Don't be an idiot. Less than 10/s is okay</p>
|
||||
<h3>Source code</h3>
