## pointToLineDistance

Returns the minimum distance between a [Point][1] and a [LineString][2], being the distance from a line the
minimum distance between the point and any segment of the `LineString`.

**Parameters**

-   `pt` **([Feature][3]&lt;[Point][4]> | [Array][5]&lt;[number][6]>)** Feature or Geometry
-   `line` **[Feature][3]&lt;[LineString][7]>** GeoJSON Feature or Geometry
-   `options` **[Object][8]** Optional parameters (optional, default `{}`)
    -   `options.units` **[string][9]** can be anything supported by turf/convertLength, eg degrees, radians, miles, or kilometers (optional, default `'kilometers'`)
    -   `options.method` **[string][9]** wehther to calculate the distance based on geodesic (spheroid) or planar (flat) method. Valid options are 'geodesic' or 'planar'. (optional, default `'geodesic'`)

**Examples**

```javascript
var pt = turf.point([0, 0]);
var line = turf.lineString([[1, 1],[-1, 1]]);

var distance = turf.pointToLineDistance(pt, line, {units: 'miles'});
//=69.11854715938406
```

Returns **[number][6]** distance between point and line
