## Snap a coordinate to the nearest road

`routing.nearest_post(RoutingNearestPostParams**kwargs)  -> NearestResult`

**post** `/api/v1/nearest`

Snap a coordinate to the nearest road

### Parameters

- `lat: float`

  Latitude

- `lng: float`

  Longitude

- `output_fields: Optional[str]`

  Comma-separated property fields to include

- `output_include: Optional[str]`

  Extra computed fields: bbox, distance, center

- `output_precision: Optional[int]`

  Coordinate decimal precision (1-15, default 7)

- `radius: Optional[int]`

  Search radius in meters (default 500, max 5000)

### Returns

- `class NearestResult: …`

  GeoJSON Point Feature representing the nearest point on the road network to the input coordinate. Used for snapping GPS coordinates to roads.

  - `geometry: GeoJsonGeometry`

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

    - `coordinates: Union[List[float], List[List[float]], List[List[List[float]]], List[List[List[List[float]]]]]`

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

      - `List[float]`

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

      - `List[List[float]]`

        Array of [lng, lat] positions

      - `List[List[List[float]]]`

        Array of linear rings / line strings

      - `List[List[List[List[float]]]]`

        Array of polygons

    - `type: Literal["Point", "LineString", "Polygon", 3 more]`

      Geometry type

      - `"Point"`

      - `"LineString"`

      - `"Polygon"`

      - `"MultiPoint"`

      - `"MultiLineString"`

      - `"MultiPolygon"`

  - `properties: Properties`

    Snap result metadata

    - `distance_m: Optional[float]`

      Distance from the input coordinate to the snapped point in meters

    - `edge_id: Optional[int]`

      ID of the road network edge that was snapped to

    - `edge_length_m: Optional[float]`

      Length of the matched road edge in meters

    - `highway: Optional[str]`

      OSM highway tag value (e.g. `residential`, `primary`, `motorway`)

    - `osm_way_id: Optional[int]`

      OSM way ID of the matched road segment

    - `surface: Optional[str]`

      OSM surface tag value (e.g. `asphalt`, `gravel`, `paved`)

  - `type: Literal["Feature"]`

    - `"Feature"`

### Example

```python
import os
from plaza import Plaza

client = Plaza(
    api_key=os.environ.get("PLAZA_API_KEY"),  # This is the default and can be omitted
)
nearest_result = client.routing.nearest_post(
    lat=0,
    lng=0,
)
print(nearest_result.geometry)
```
