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.
Output format, should be "geojson", "array" or "topocentric-array". (Default: "array")
