Get feature by type and ID

class GeoJsonFeature { geometry, properties, type, id }

GeoJSON Feature representing an OSM element. Tags from the original OSM element are flattened directly into properties (not nested under a tags key). Metadata fields @type and @id identify the OSM element type and ID within properties.

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[Float] | Array[Array[Float]] | Array[Array[Array[Float]]] | Array[Array[Array[Array[Float]]]]

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

One of the following:

Array[Float]

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

Array[Array[Float]]

Array of [lng, lat] positions

Array[Array[Array[Float]]]

Array of linear rings / line strings

Array[Array[Array[Array[Float]]]]

Array of polygons

type: :Point | :LineString | :Polygon | 3 more

Geometry type

One of the following:

:Point

:LineString

:Polygon

:MultiPoint

:MultiLineString

:MultiPolygon

properties: Hash[Symbol, untyped]

OSM tags flattened as key-value pairs, plus @type (node/way/relation) and @id (OSM ID) metadata fields. May include distance_m for proximity queries.

type: :Feature

Always Feature

id: String

Compound identifier in type/osm_id format
