# new CoordinateRegion(center, span)

A rectangular geographic region that centers around a latitude and longitude coordinate.

```
constructor(center?: CoordinateData, span?: CoordinateSpanData);
```

## Parameters

`center`

A [`Coordinate`](/documentation/MapKitJS/Coordinate) that’s the center point of the region.

`span`

A [`CoordinateSpan`](/documentation/MapKitJS/CoordinateSpan) that represents the amount of map to display. The span also defines the current zoom level that the map object uses.

## Discussion

Create a coordinate region by passing a center coordinate and span to the constructor.

```javascript
const coordinate = new mapkit.Coordinate(37.415, -122.048333); // latitude, longitude
const span = new mapkit.CoordinateSpan(.016, .016); // latitude delta, longitude delta
const region = new mapkit.CoordinateRegion(coordinate, span);
```
