## Look up elevation at one or more points

`elevation().lookupPost(ElevationLookupPostParamsparams = ElevationLookupPostParams.none(), RequestOptionsrequestOptions = RequestOptions.none()) : ElevationLookupResult`

**post** `/api/v1/elevation`

Look up elevation at one or more points

### Parameters

- `params: ElevationLookupPostParams`

  - `format: Optional<String>`

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

  - `lat: Optional<Double>`

    Latitude (single point)

  - `lng: Optional<Double>`

    Longitude (single point)

  - `locations: Optional<String>`

    Pipe-separated lng,lat pairs (batch)

  - `outputFields: Optional<String>`

    Comma-separated property fields to include

  - `outputInclude: Optional<String>`

    Extra computed fields: bbox, center

  - `outputPrecision: Optional<Long>`

    Coordinate decimal precision (1-15, default 7)

### Returns

- `class ElevationLookupResult:`

  GeoJSON Point Feature with a 3D coordinate [lng, lat, elevation] per RFC 7946 §3.1.1. The elevation is also available in `properties.elevation_m` for convenience.

  - `geometry: GeoJsonGeometry`

    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`

    - `elevationM: Double`

      Elevation in meters above mean sea level (WGS84 EGM96 geoid)

  - `type: Type`

    - `FEATURE("Feature")`

### Example

```kotlin
package com.plazafyi.example

import com.plazafyi.client.PlazaClient

import com.plazafyi.models.elevation.ElevationLookupResult

fun main() {
    val client: PlazaClient = PlazaOkHttpClient.fromEnv()

    val elevationLookupResult: ElevationLookupResult = client.elevation().lookupPost()
}
```
