# boundingMapRect

The bounding rectangle of the circular area.

## Declaration

```swift
var boundingMapRect: MKMapRect { get }
```

## Discussion

Discussion As latitude values move away from the equator and toward the poles, the physical distance between map points gets smaller. This means that the map needs more map points to represent the same distance. As a result, the bounding rectangle of a circle overlay gets larger as the center point of that circle moves away from the equator and toward the poles.
