README
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
https://packagist.org/packages/jmbtechnologylimited/osmaths
composer require jmbtechnologylimited/osmaths
Use
$en = new EastingNorthing($inEasting, $inNorthing);
$latlng = $en->toLatLngOSGB36()->toLatLngWGS84();
print $latlng->getLat();
print $latlng->getLng();
Code Standards
Every object is immutable, so you can pass around data objects without worrying they will be changed.
