## sector
|
|
|
|
Creates a circular sector of a circle of given radius and center [Point][1],
|
|
between (clockwise) bearing1 and bearing2; 0 bearing is North of center point, positive clockwise.
|
|
|
|
**Parameters**
|
|
|
|
- `center` **[Coord][2]** center point
|
|
- `radius` **[number][3]** radius of the circle
|
|
- `bearing1` **[number][3]** angle, in decimal degrees, of the first radius of the sector
|
|
- `bearing2` **[number][3]** angle, in decimal degrees, of the second radius of the sector
|
|
- `options` **[Object][4]** Optional parameters (optional, default `{}`)
|
|
- `options.units` **[string][5]** miles, kilometers, degrees, or radians (optional, default `'kilometers'`)
|
|
- `options.steps` **[number][3]** number of steps (optional, default `64`)
|
|
- `options.properties` **Properties** Translate properties to Feature Polygon (optional, default `{}`)
|
|
|
|
**Examples**
|
|
|
|
```javascript
|
|
var center = turf.point([-75, 40]);
|
|
var radius = 5;
|
|
var bearing1 = 25;
|
|
var bearing2 = 45;
|
|
|
|
var sector = turf.sector(center, radius, bearing1, bearing2);
|
|
|
|
//addToMap
|
|
var addToMap = [center, sector];
|
|
```
|
|
|
|
Returns **[Feature][6]<[Polygon][7]>** sector polygon
