Reverse geocode a coordinate

client.Geocode.ReversePost(ctx, body) (*ReverseGeocodeResult, error)

POST/api/v1/geocode/reverse

Reverse geocode a coordinate

ParametersExpand Collapse

body GeocodeReversePostParams

Format param.Field[string]optional

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

Lang param.Field[string]optional

Language code for localized names (e.g. en, de, fr)

Lat param.Field[float64]optional

Legacy shorthand. Latitude. Use near param instead.

Layer param.Field[string]optional

Filter by layer: house or poi

Limit param.Field[int64]optional

Maximum results (default 1, max 20)

Lng param.Field[float64]optional

Legacy shorthand. Longitude. Use near param instead.

Near param.Field[string]optional

Point geometry for reverse geocode (lat,lng or GeoJSON). Alternative to lat/lng params.

Radius param.Field[int64]optional

Search radius in meters (default 200, max 5000)

ReturnsExpand Collapse

type ReverseGeocodeResult struct{…}

GeoJSON FeatureCollection of reverse geocoding results, ordered by distance from the query point. Content-Type: application/geo+json.

Features []GeocodingFeature

Reverse geocoding results ordered by distance

Geometry GeoJsonGeometry

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

Coordinates GeoJsonGeometryCoordinatesUnion

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

One of the following:

type GeoJsonGeometryCoordinatesPoint []float64

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

type GeoJsonGeometryCoordinatesLineStringOrMultiPoint [][]float64

Array of [lng, lat] positions

type GeoJsonGeometryCoordinatesPolygonOrMultiLineString [][][]float64

Array of linear rings / line strings

type GeoJsonGeometryCoordinatesMultiPolygon [][][][]float64

Array of polygons

Type GeoJsonGeometryType

Geometry type

One of the following:

const GeoJsonGeometryTypePoint GeoJsonGeometryType = "Point"

const GeoJsonGeometryTypeLineString GeoJsonGeometryType = "LineString"

const GeoJsonGeometryTypePolygon GeoJsonGeometryType = "Polygon"

const GeoJsonGeometryTypeMultiPoint GeoJsonGeometryType = "MultiPoint"

const GeoJsonGeometryTypeMultiLineString GeoJsonGeometryType = "MultiLineString"

const GeoJsonGeometryTypeMultiPolygon GeoJsonGeometryType = "MultiPolygon"

Properties GeocodingFeatureProperties

Geocoding result properties
