    },
    "x": 86.925278,
    "y": 27.988333,
    "z": 8744
  }
}

A structure containing a point including an elevation value (defined as Z).

Properties

Name	Type	Required	Restrictions	Description
`point`	`Point`		none	The point containing the elevation.

ElevationInfo

Example
Use dark colors for code blocksCopy
{
  "relativeTo": "meanSeaLevel"
}

A structure containing human readable metadata about the specified point.

Properties

Name Type Required Restrictions Description

Name	Type	Required	Restrictions	Description
`relativeTo`	`string`		none	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.
