## Look up elevation at one or more points

`client.elevation.lookupPost(ElevationLookupPostParamsparams?, RequestOptionsoptions?): ElevationLookupResult`

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

Look up elevation at one or more points

### Parameters

- `params: ElevationLookupPostParams`

  - `format?: string`

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

  - `lat?: number`

    Latitude (single point)

  - `lng?: number`

    Longitude (single point)

  - `locations?: string`

    Pipe-separated lng,lat pairs (batch)

  - `outputFields?: string`

    Comma-separated property fields to include

  - `outputInclude?: string`

    Extra computed fields: bbox, center

  - `outputPrecision?: number`

    Coordinate decimal precision (1-15, default 7)

### Returns

- `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: Array<number> | Array<Array<number>> | Array<Array<Array<number>>> | Array<Array<Array<Array<number>>>>`

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

      - `Array<number>`

      - `Array<Array<number>>`

      - `Array<Array<Array<number>>>`

      - `Array<Array<Array<Array<number>>>>`

    - `type: "Point" | "LineString" | "Polygon" | 3 more`

      Geometry type

      - `"Point"`

      - `"LineString"`

      - `"Polygon"`

      - `"MultiPoint"`

      - `"MultiLineString"`

      - `"MultiPolygon"`

  - `properties: Properties`

    - `elevation_m: number`

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

  - `type: "Feature"`

    - `"Feature"`

### Example

```typescript
import Plaza from '@plazafyi/sdk';

const client = new Plaza({
  apiKey: process.env['PLAZA_API_KEY'], // This is the default and can be omitted
});

const elevationLookupResult = await client.elevation.lookupPost();

console.log(elevationLookupResult.geometry);
```

#### Response

```json
{
  "geometry": {
    "coordinates": [
      2.3522,
      48.8566
    ],
    "type": "Point"
  },
  "properties": {
    "elevation_m": 35.2
  },
  "type": "Feature"
}
