client.Elements.Nearby(ctx, query) (*FeatureCollection, error)

GET/api/v1/features/nearby

Find features near a geographic point

ParametersExpand Collapse

query ElementNearbyParams

Lat param.Field[float64]optional

Legacy shorthand. Latitude (-90 to 90). Use near param instead.

Limit param.Field[int64]optional

Maximum results (default 20, max 100)

Lng param.Field[float64]optional

Legacy shorthand. Longitude (-180 to 180). Use near param instead.

Near param.Field[string]optional

Point geometry for proximity search (lat,lng or GeoJSON). Alternative to lat/lng params.

OutputBuffer param.Field[float64]optional

Buffer geometry by meters

OutputCentroid param.Field[bool]optional

Replace geometry with centroid

OutputFields param.Field[string]optional

Comma-separated property fields to include

OutputGeometry param.Field[bool]optional

Include geometry (default true)

OutputInclude param.Field[string]optional

Extra computed fields: bbox, distance, center

OutputPrecision param.Field[int64]optional

Coordinate decimal precision (1-15, default 7)

OutputSimplify param.Field[float64]optional

Simplify geometry tolerance in meters

OutputSort param.Field[string]optional

Sort by: distance, name, osm_id

Radius param.Field[int64]optional

Search radius in meters (default 500, max 10000)

type FeatureCollection struct{…}

GeoJSON FeatureCollection (RFC 7946). For paginated endpoints, metadata is returned in HTTP response headers rather than the body:

Header	Description
X-Limit	Requested result limit
X-Has-More	true if more results exist
X-Next-Cursor	Opaque cursor for next page (cursor pagination)
X-Next-Offset	Numeric offset for next page (offset pagination)
Link	RFC 8288 rel="next" link to the next page

Content-Type is application/geo+json.

Features []GeoJsonFeature

Array of GeoJSON Feature objects

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 map[string, unknown]

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.
