Breasal

A Ruby gem that converts both British and Irish Eastings and northing to WGS84 latitude and longitude.

Based on the work by Andrew Sprinz at Lambeth Council, and created in anger as part of work on UK Postcodes

Breasal is the Welsh and Cornish God of all earth, so I thought him suitably Celtic to cover all the British isles.

Installation

Add this line to your application's Gemfile:

gem 'breasal'

And then execute:

$ bundle

Or install it yourself as:

$ gem install breasal

Usage

Provide an easting, northing and coordinate type (either :gb or :ie - default is :gb):

en = Breasal::EastingNorthing.new(easting: 412617, northing: 308885, type: :gb)

Get the WGS84 latlng:

en.to_wgs84 # => {:latitude=>52.67752501534847, :longitude=>-1.8148108086293673}
