Mapnik Legendary

Mapnik Legendary is a small utility to help with generating legends (aka map keys) from Mapnik stylesheets. You describe in a config file which attributes, and which zoom level(s) you want an image for, and it reads the stylesheet and spits out .png files. It uses the ruby-mapnik bindings to load the stylesheets and mess around with the datasources, so you don't actually need any of the shapefiles or database connections to make this work.

• Ruby-Mapnik bindings >= 0.2.0
• mapnik 2.x and ruby (both required for Ruby-Mapnik)

You can install the gem from rubygems:

gem install mapnik_legendary

Alternatively, you can add the gem to your project's Gemfile

gem mapnik_legendary

For full options, run

mapnik_legendary -h
