Library to normalize Geographic Coordinate System (GCS) so the coordinate will be in the range of

```
-180 < longitude < 180
-90  < latitude  < 90

```

Installation
------------

[](#installation)

Install with composer

```
composer require zackad/normalize-coordinate
```

Usage

```
use Zackad\GIS\Coordinate\Normalize as Coordinate;

$coord = new Coordinate;

echo $coord->normalizeLongitude(200);
// will output '-160'

echo $coord->normalizeLatitude(-200);
// will output '20'

echo $coord->normalize(541.45, -90.55);
// will output '[-178.55, -89.45]'
```
