## API Reference

<a name="module_Terraformer"></a>

## Terraformer

* [Terraformer](#module_Terraformer)
    * [.wktToGeoJSON(WKT)](#module_Terraformer.wktToGeoJSON) ⇒ <code>object</code>
    * [.geojsonToWKT(GeoJSON)](#module_Terraformer.geojsonToWKT) ⇒ <code>string</code>

<a name="module_Terraformer.wktToGeoJSON"></a>

### Terraformer.wktToGeoJSON(WKT) ⇒ <code>object</code>
Converts a [WKT](https://en.wikipedia.org/wiki/Well-known_text_representation_of_geometry) geometry into a GeoJSON geometry.

**Kind**: static method of [<code>Terraformer</code>](#module_Terraformer)  
**Returns**: <code>object</code> - GeoJSON.

```js
import { wktToGeoJSON } from "@terraformer/wkt"

wktToGeoJSON("POINT (-122.6764 45.5165)");

>> { "type": "Point", "coordinates": [ -122.6764, 45.5165 ] }
```  

| Param | Type | Description |
| --- | --- | --- |
| WKT | <code>string</code> | The input WKT geometry. |

<a name="module_Terraformer.geojsonToWKT"></a>

### Terraformer.geojsonToWKT(GeoJSON) ⇒ <code>string</code>
Converts a GeoJSON geometry or GeometryCollection into a [WKT](https://en.wikipedia.org/wiki/Well-known_text_representation_of_geometry) string.

**Kind**: static method of [<code>Terraformer</code>](#module_Terraformer)  
**Returns**: <code>string</code> - WKT.
```js
import { geojsonToWKT } from "@terraformer/wkt"

const geojsonPoint = {
  "type": "Point",
  "coordinates": [-122.6764, 45.5165]
}

geojsonToWKT(geojsonPoint)

>> "POINT (-122.6764 45.5165)"
```  

| Param | Type | Description |
| --- | --- | --- |
| GeoJSON | <code>object</code> | The input GeoJSON geometry or GeometryCollection. |
