GlobalMapTiles

Ruby port of the script globalmaptiles.py from Tiles à la Google Maps: Coordinates, Tile Bounds and Projection

Lon/Lat convention was chosen over Lat/Lon as it's the convention of GeoJSON.

Add this line to your application's Gemfile:

gem "global_map_tiles"

And then execute:

$ bundle install

Or install it yourself as:

$ gem install global_map_tiles

require "global_map_tiles"

mercator = GlobalMapTiles::GlobalMercator.new
puts mercator.lon_lat_to_meters(13.24, 52.31)
puts mercator.meters_to_lon_lat(1473870.058102942, 6856372.69101939)

See all the examples in spec/global_mercator_spec.rb
