**Parameters**
|
|
|
|
- `bbox` **[Array](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Array)<[number](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Number)>** extent in [minX, minY, maxX, maxY] order
|
|
- `cellWidth` **[number](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Number)** of each cell, in units
|
|
- `cellHeight` **[number](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Number)** of each cell, in units
|
|
- `options` **[Object](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Object)** Optional parameters (optional, default `{}`)
|
|
- `options.units` **[string](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/String)** units ("degrees", "radians", "miles", "kilometers") that the given cellWidth
|
|
and cellHeight are expressed in. Converted at the southern border. (optional, default `'kilometers'`)
|
|
- `options.mask` **[Feature](https://tools.ietf.org/html/rfc7946#section-3.2)<([Polygon](https://tools.ietf.org/html/rfc7946#section-3.1.6) \| [MultiPolygon](https://tools.ietf.org/html/rfc7946#section-3.1.7))>?** if passed a Polygon or MultiPolygon,

the grid Points will be created only inside it
|
|
- `options.properties` **[Object](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Object)** passed to each point of the grid (optional, default `{}`)

|
```javascript
|
|
var bbox = [-95, 30 ,-85, 40];
|
|
var cellWidth = 50;
|
|
var cellHeight = 20;
|
|
var options = {units: 'miles'};
|
|
|
|
var rectangleGrid = turf.rectangleGrid(bbox, cellWidth, cellHeight, options);
|
|
|
|
//addToMap
|
|
var addToMap = [rectangleGrid]
|
|
```
|
|
|
|
Returns **[FeatureCollection](https://tools.ietf.org/html/rfc7946#section-3.3)<[Polygon](https://tools.ietf.org/html/rfc7946#section-3.1.6)>** a grid of polygons
