## midpoint
|
|
|
|
Takes two [points][1] and returns a point midway between them.
|
|
The midpoint is calculated geodesically, meaning the curvature of the earth is taken into account.
|
|
|
|
**Parameters**
|
|
|
|
- `point1` **[Coord][2]** first point
|
|
- `point2` **[Coord][2]** second point
|
|
|
|
**Examples**
|
|
|
|
```javascript
|
|
var point1 = turf.point([144.834823, -37.771257]);
|
|
var point2 = turf.point([145.14244, -37.830937]);
|
|
|
|
var midpoint = turf.midpoint(point1, point2);
|
|
|
|
//addToMap
|
|
var addToMap = [point1, point2, midpoint];
|
|
midpoint.properties['marker-color'] = '#f00';
|
|
```
|
|
|
|
Returns **[Feature][3]<[Point][4]>** a point midway between `pt1` and `pt2`
