Returns the elevation from a given input coordinate.
Returns the elevation in meters at a given longitude and latitude within the WGS84 coordinate system.
By default the elevation is measured with respect to the Earth's mean sea level. It takes into account the local variations in gravity and provides a consistent vertical reference.
If the relative query parameter is set to ellipsoid, the elevation will be measured with respect to the ellipsoid. This is a mathematical model that approximates the shape of the Earth. It does not consider local variations in gravity and is commonly used in GPS positioning.
Note: You cannot permanently store elevations. Please see the Terms of use.

relativeTo
The reference position (datum) from which to measure elevation. The valid values are:
- meanSeaLevel: The elevation above or below the WGS84 geoid reference surface, which is approximately the mean sea level. It takes into account the local variations in gravity and provides a consistent vertical reference.
- ellipsoid: Ellipsoidal height is measured with respect to an ellipsoid, which is a mathematical model that approximates the shape of the Earth. It does not consider local variations in gravity and is commonly used in GPS positioning.
- Default
- meanSeaLevel
Enumerated values
token
The authentication token, used to access the elevation service.
The token parameter can be either an API Key or short-lived token.
Alternatively, you can supply a token in the request header with one of the following keys using the "Bearer" scheme:
Authorization: Bearer <YOUR _TOKEN > X-Esri- Authorization : Bearer <YOUR _TOKEN >
The provided token must be created from an ArcGIS Location Platform account and have the necessary premium privilege to use the elevation service.

f
Optional, case-sensitive parameter to specify the format in which responses are given. Can either be json or pjson.
- Default
- json
