Goosfraba GPS
=============

[](#goosfraba-gps)

A simple wrapper for GPS coordinates. Provides basic functionalities like distance calculation between two givens points, interpolation of the coordinates between two givens points and antipodes calculation. It uses `bcmath` PHP extension for calculation (for eligible calculations only).

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

[](#installation)

Use `composer`

```
composer require goosfraba/gps
```

Usage
-----

[](#usage)

### Coordinates instantiation and basic usage

[](#coordinates-instantiation-and-basic-usage)

```
use Goosfraba\Gps\GpsCoordinates;
$coordinates = GpsCoordinates::createFromDegrees(38.8, -77.1);
// or
$coordinates = GpsCoordinates::createFromRadians(0.677187749773799875846392, -1.3456488532876281038081655);

// accessing coordinates in radians
$latitudeInRadians = $coordinates->latitudeInRadians();
$longitudeInRadians = $coordinates->longitudeInRadians();

// accessing coordinates in degrees
$latitudeInDegrees = $coordinates->latitudeInDegrees();
$longitudeInDegrees = $coordinates->longitudeInDegrees();
```

### Calculating distance between two givens points

[](#calculating-distance-between-two-givens-points)

```
use Goosfraba\Gps\GpsCoordinates;

$coordinate1 = GpsCoordinates::createFromDegrees(51.5, 0);
$coordinate2 = GpsCoordinates::createFromDegrees(38.8, -77.1);

$distanceInMeters = $coordinate1->disntaceTo($coordinate2);
```

### Coordinates interpolation between two givens points at given distance

[](#coordinates-interpolation-between-two-givens-points-at-given-distance)

```
use Goosfraba\Gps\GpsCoordinates;

$coordinate1 = GpsCoordinates::createFromDegrees(51.5, 0);
$coordinate2 = GpsCoordinates::createFromDegrees(38.8, -77.1);

$midPointCoordinates = $coordinate1->pointBetween($coordinate2);
$coordinatesAt10Percent = $coordinate1->pointBetween($coordinate2, $coordinate1->distanceTo($coordinate2) / 10);
```

### Antipodes calculation

[](#antipodes-calculation)

```
use Goosfraba\Gps\GpsCoordinates;

$coordinate = GpsCoordinates::createFromDegrees(51.5, 0);
$antipodes = $coordinate->antipodes();
```

### Tests

[](#tests)

```
