ReturnsExpand Collapse
ElevationLookupResult = object { geometry, properties, type }

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.

geometry: GeoJsonGeometry { coordinates, type }

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

coordinates: array of number or array of array of number or array of array of array of number or array of array of array of array of number

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

One of the following:
Point = array of number

[longitude, latitude] or [longitude, latitude, elevation]

LineStringOrMultiPoint = array of array of number

Array of [lng, lat] positions

PolygonOrMultiLineString = array of array of array of number

Array of linear rings / line strings

MultiPolygon = array of array of array of array of number

Array of polygons

type: "Point" or "LineString" or "Polygon" or 3 more

Geometry type

One of the following:
"Point"
"LineString"
"Polygon"
"MultiPoint"
"MultiLineString"
"MultiPolygon"
properties: object { elevation_m }
elevation_m: number

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

type: "Feature"
