## Find features near a geographic point

`FeatureCollection elements().nearbyPost(ElementNearbyPostParamsparams = ElementNearbyPostParams.none(), RequestOptionsrequestOptions = RequestOptions.none())`

**post** `/api/v1/features/nearby`

Find features near a geographic point

### Parameters

- `ElementNearbyPostParams params`

  - `Optional<Double> lat`

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

  - `Optional<Long> limit`

    Maximum results (default 20, max 100)

  - `Optional<Double> lng`

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

  - `Optional<String> near`

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

  - `Optional<Double> outputBuffer`

    Buffer geometry by meters

  - `Optional<Boolean> outputCentroid`

    Replace geometry with centroid

  - `Optional<String> outputFields`

    Comma-separated property fields to include

  - `Optional<Boolean> outputGeometry`

    Include geometry (default true)

  - `Optional<String> outputInclude`

    Extra computed fields: bbox, distance, center

  - `Optional<Long> outputPrecision`

    Coordinate decimal precision (1-15, default 7)

  - `Optional<Double> outputSimplify`

    Simplify geometry tolerance in meters

  - `Optional<String> outputSort`

    Sort by: distance, name, osm_id

  - `Optional<Long> radius`

    Search radius in meters (default 500, max 10000)

### Returns

- `class FeatureCollection:`

  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`.

  - `List<GeoJsonFeature> features`

    Array of GeoJSON Feature objects

    - `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.

        - `List<double>`

        - `List<List<double>>`

        - `List<List<List<double>>>`

        - `List<List<List<List<double>>>>`

      - `Type type`

        Geometry type

        - `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`

      - `FEATURE("Feature")`

    - `Optional<String> id`

      Compound identifier in `type/osm_id` format

  - `Type type`

    Always `FeatureCollection`

    - `FEATURE_COLLECTION("FeatureCollection")`

### Example

```java
package com.plazafyi.example;

import com.plazafyi.client.PlazaClient;
import com.plazafyi.client.okhttp.PlazaOkHttpClient;
import com.plazafyi.models.FeatureCollection;
import com.plazafyi.models.elements.ElementNearbyPostParams;

public final class Main {
    private Main() {}

    public static void main(String[] args) {
        PlazaClient client = PlazaOkHttpClient.fromEnv();

        FeatureCollection featureCollection = client.elements().nearbyPost();
    }
}
```
