# Elevation

{% hint style="info" %}
This API is available on the **Pro** plan or higher
{% endhint %}

Query the elevation above sea level for a given coordinate or coordinates with the `/elevation` end point. Post an array of one or more lat/lng coordinates to obtain the elevation above sea level at the given point.

The end point can return three format response types, based on the `format` query parameter value:

* geojson: a valid GeoJSON document
* array: an array of elevations not including the corresponding lat/lng coordinate (array order is preserved in the response)
* topocentric-array: an array of \[lat, lng, elevation] values

### Data Source

Elevation data is obtained from the public [Terrain Tiles](https://registry.opendata.aws/terrain-tiles/) data set.
