## Look up elevation at one or more points

`elevation.lookup_post(**kwargs) -> ElevationLookupResult`

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

Look up elevation at one or more points

### Parameters

- `format_: String`

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

- `lat: Float`

  Latitude (single point)

- `lng: Float`

  Longitude (single point)

- `locations: String`

  Pipe-separated lng,lat pairs (batch)

- `output_fields: String`

  Comma-separated property fields to include

- `output_include: String`

  Extra computed fields: bbox, center

- `output_precision: Integer`

  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: Array[Float] | Array[Array[Float]] | Array[Array[Array[Float]]] | Array[Array[Array[Array[Float]]]]`

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

      - `Array[Float]`

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

      - `Array[Array[Float]]`

        Array of [lng, lat] positions

      - `Array[Array[Array[Float]]]`

        Array of linear rings / line strings

      - `Array[Array[Array[Array[Float]]]]`

        Array of polygons

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

      Geometry type

      - `:Point`

      - `:LineString`

      - `:Polygon`

      - `:MultiPoint`

      - `:MultiLineString`

      - `:MultiPolygon`

  - `properties: { elevation_m}`

    - `elevation_m: Float`

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

  - `type: :Feature`

    - `:Feature`

### Example

```ruby
require "plaza"

plaza = Plaza::Client.new(
  api_key: "My API Key",
  environment: "local" # defaults to "production"
)

elevation_lookup_result = plaza.elevation.lookup_post

puts(elevation_lookup_result)
```

#### Response

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