class ElevationLookupResult:

GeoJSON Point Feature with a 3D coordinate [lng, lat, elevation] per RFC 7946 §3.1.1. The elevation is also available in properties.elevation_m for convenience.

required GeoJsonGeometry Geometry

GeoJSON Geometry object per RFC 7946. Coordinates use [longitude, latitude] order. 3D coordinates [lng, lat, elevation] are used for elevation endpoints.

required Coordinates Coordinates

Coordinates array. Nesting depth varies by geometry type: Point = [lng, lat], LineString = [[lng, lat], ...], Polygon = [[[lng, lat], ...], ...], etc.

One of the following:
IReadOnlyList<Double>
IReadOnlyList<IReadOnlyList<Double>>
IReadOnlyList<IReadOnlyList<IReadOnlyList<Double>>>
IReadOnlyList<IReadOnlyList<IReadOnlyList<IReadOnlyList<Double>>>>
required Type Type

required Properties Properties
required Double ElevationM

Elevation in meters above mean sea level (WGS84 EGM96 geoid)

required Type Type
