# MapRect

A rectangular region, in map units, of a two-dimensional map projection.

## Declaration

```data
class MapRect implements MapRectData
```

## Mentioned in

Migrating from Version 5 to Version 6 MapKit JS 6

## Overview

Overview Use a mapkit.MapRect to represent a rectangular region within a map projection. Map units are a value from 0 to 1 that represent an interpolated location within the height or width of the full map projection.

## Topics

### Creating a map rectangle
