OSMaths
=======

[](#osmaths)

This is a PHP library for doing the conversations around the coordinate systems used for Ordnance Survey Open Data only.

Most of the Open Data comes in Easting/Northing. It needs converting to Latitude and Longitude. Further more, this is in OSGB36, and you probably want your Lat/Lng in WGS84, which is the same projection Open Street Map and Google Maps use.

I am not an expert in mapping systems. I cobbled this together from other sources based on my needs. I would love to retire it if someone else has a PHP library that does this with a permissive license.

Install via Composer
--------------------

[](#install-via-composer)

```
composer require jmbtechnologylimited/osmaths

```

Use
---

[](#use)

```
$en = new EastingNorthing($inEasting, $inNorthing);
$latlng = $en->toLatLngOSGB36()->toLatLngWGS84();
print $latlng->getLat();
print $latlng->getLng();

```

Code Standards
--------------

[](#code-standards)

Every object is immutable, so you can pass around data objects without worrying they will be changed.

License
-------

[](#license)

BSD License

Note this software does not contain any actual data from the Ordnance Survey. You must get that yourself, and agree to their license to.
