Earlier this year, Andy embarked on a rewrite of the OpenStreetMap standard Mapnik stylesheets, porting them to the CartoCSS styling language. This opens the door for developing the styles using TileMill, as well as making them easy to customize for other projects.
In this session Andy will discuss some of the background behind the rewrite, tips that he’s picked up, tricks that were developed, and advice on the common pitfalls when styling OSM data in TileMill. He’ll also explain how to wrangle the stylesheets to suit your own projects and how to help further improve our cartography.
