Elevation

Determine the elevation above sea level for given coordinates

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 data set.
