# MKMapRect

A rectangular area on a two-dimensional map projection.

## Declaration

```swift
struct MKMapRect
```

## Overview

Overview If you project the curved surface of the globe onto a flat surface, what you get is a two-dimensional version of a map where longitude lines appear to be parallel. Such maps are often used to show the entire surface of the globe all at once. An MKMapRect data structure represents a rectangular area as seen on this two-dimensional map.

## Topics

### Creating a map rectangle

- [init()](mapkit/mkmaprect/init().md)
- [init(origin:size:)](mapkit/mkmaprect/init(origin:size:).md)
- [init(x:y:width:height:)](mapkit/mkmaprect/init(x:y:width:height:).md)
- [init(_:)](mapkit/mkcoordinateregion/init(_:).md)
