# new BoundingRegion(northLatitude, eastLongitude, southLatitude, westLongitude)

Creates a rectangular bounding region, which the latitude and longitude coordinates of the rectangle’s northeast and southwest corners define.

```
constructor(
    northLatitude?: number,
    eastLongitude?: number,
    southLatitude?: number,
    westLongitude?: number,
);
```

## Parameters

`northLatitude`

The north latitude of the bounding region.

`eastLongitude`

The east longitude of the bounding region.

`southLatitude`

The south latitude of the bounding region.

`westLongitude`

The west longitude of the bounding region.

## Discussion

The example below creates a new bounding region by passing the required longitude and latitude coordinates to the constructor:

```javascript
const region = new mapkit.BoundingRegion(northLatitude, eastLongitude, southLatitude, westLongitude);
```
