POST/api/v1/isochrone

Calculate an isochrone from a point

ParametersExpand Collapse

RoutingIsochronePostParams params

double lat

Latitude

double lng

Longitude

double time

Travel time in seconds (1-7200)

Optional<String> format

Response format: json (default), geojson, csv, ndjson

ReturnsExpand Collapse

class RoutingIsochronePostResponse:

GeoJSON Feature or FeatureCollection representing isochrone polygons — areas reachable within the specified travel time(s). Single time value returns a Feature; comma-separated times return a FeatureCollection with one polygon per contour.

Optional<List<GeoJsonFeature>> features

Array of isochrone polygon Features (multi-contour only)

GeoJsonGeometry geometry

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

Optional<String> id

Compound identifier in type/osm_id format

Optional<GeoJsonGeometry> geometry

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.

POINT("Point")

LINE_STRING("LineString")

POLYGON("Polygon")

MULTI_POINT("MultiPoint")

MULTI_LINE_STRING("MultiLineString")

MULTI_POLYGON("MultiPolygon")

Optional<Properties> properties

Isochrone metadata

Optional<Double> areaM2

Area of the isochrone polygon in square meters (multi-contour features only)

Optional<Double> maxCostS

Maximum actual travel cost in seconds to the isochrone boundary (single contour only)

Optional<Mode> mode

Travel mode used for the isochrone calculation

One of the following:

AUTO("auto")

FOOT("foot")

BICYCLE("bicycle")

Optional<Double> timeSeconds

Travel time budget in seconds

Optional<Long> verticesReached

Number of road network vertices within the isochrone

Optional<Type> type

Feature for single contour, FeatureCollection for multiple contours

One of the following:

FEATURE("Feature")

FEATURE_COLLECTION("FeatureCollection")
