  - `geometry: GeoJsonGeometry`

    - `coordinates: Array[Float] | Array[Array[Float]] | Array[Array[Array[Float]]] | Array[Array[Array[Array[Float]]]]`

      GeoJSON coordinates array (nesting depth varies by geometry type)

      - `Array[Float]`

      - `Array[Array[Float]]`

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

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

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

      - `:Point`

      - `:LineString`

      - `:Polygon`

      - `:MultiPoint`

      - `:MultiLineString`

      - `:MultiPolygon`

  - `properties: { elevation_m}`

    - `elevation_m: Float`

      Elevation in meters above mean sea level

  - `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

puts(elevation_lookup_result)
```
