Geographic Point
================

[](#geographic-point)

GeoPoint represents a geographic point for PHP including conversion, point-to-point distance, and bounding-box calculations.

Usage
-----

[](#usage)

```
$statueOfLibertyPoint = new GeoPoint(40.689604, -74.04455, GeoPoint::DEGREES);

```

Constructor options
-------------------

[](#constructor-options)

- `latitude` -- Latitude
- `longitude` -- Longitude
- `format` -- The format of the passed-in lat/lon as GeoPoint::DEGREES or GeoPoint::RADIANS

Methods
-------

[](#methods)

- `getLatitude()`: Return the point's latitude per the format of the point (GeoPoint::DEGREES or GeoPoint::RADIANS)
- `getLongitude()`: Return the point's longitude per the format of the point (GeoPoint::DEGREES or GeoPoint::RADIANS)
- `distanceTo(GeoPoint, kmOrMiles)`: Calculate the distance to another `GeoPoint` instance using either GeoPoint::KILOMETERS or GeoPoint::MILES.
- `boundingCoordinates(distance, radius, kmOrMiles)`: Calculates the bounding coordinates of `distance` from the point and returns an array with the SW and NE points of the bounding box . If `radius` is not provided, the radius of the Earth will be used. The distance is calculated in kilometers unless kmOrMiles is set to GeoPoint::MILES.

Static Methods
--------------

[](#static-methods)

- `GeoPoint::degreesToRadians(value)`: Converts `value` in degrees to radians
- `GeoPoint::radiansToDegrees(value)`: Converts `value` in radians to degrees
- `GeoPoint::milesToKilometers(value)`: Converts `value` in miles to kilometers
- `GeoPoint::kilometersToMiles(value)`: Converts `value` in kilometers to miles

Running Tests
-------------

[](#running-tests)

`php composer.phar test`

Background
----------

[](#background)

This is inspired by [David Wood's JavaScript port](https://github.com/davidwood/node-geopoint) of the Java code presented in [Finding Points Within a Distance of a Latitude/Longitude Using Bounding Coordinates](http://janmatuschek.de/LatitudeLongitudeBoundingCoordinates) by [Jan Philip Matuschek](http://janmatuschek.de/Contact).
