# 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.

## Declaration

```data
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

Discussion The example below creates a new bounding region by passing the required longitude and latitude coordinates to the constructor: const region = new mapkit.BoundingRegion(northLatitude, eastLongitude, southLatitude, westLongitude);
