GET/api/v1/features/{type}/{id}

Get feature by type and ID

ParametersExpand Collapse

params: ElementRetrieveParams

type: String

id: Optional<Long>

ReturnsExpand Collapse

class GeoJsonFeature:

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

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

coordinates: Coordinates

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

One of the following:

List<Double>

List<List<Double>>

List<List<List<Double>>>

List<List<List<List<Double>>>>

type: Type

Geometry type

One of the following:

POINT("Point")

LINE_STRING("LineString")

POLYGON("Polygon")

MULTI_POINT("MultiPoint")

MULTI_LINE_STRING("MultiLineString")

MULTI_POLYGON("MultiPolygon")

properties: Properties

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: Type

Always Feature

id: Optional<String>

Compound identifier in type/osm_id format
