# CoordinateSpan

The width and height of a map region.

## Declaration

```data
class CoordinateSpan implements CoordinateSpanData
```

## Overview

Overview You use the delta values in a coordinate span to indicate the desired zoom level of the map. Smaller delta values correspond to a higher zoom level. The span in this class refers to the width and height of a region, with distances as degrees of latitude and longitude.
