Shaping OpenStreetMap into Global Basemaps

A session at FOSS4G North America 2013

Wednesday 22nd May, 2013

10:30am to 11:00am (CST)

OpenStreetMap is an incredible project and resource powered by volunteers around the world. The community and the information we as OSM collectively curate is growing rapidly into the biggest, most
complete repository of open geographic knowledge. However the breadth, precision, and organic nature of OSM data makes it a challenge to work with at scale. I will explore the main problems you will encounter working with the entire OSM Planet and detail the solutions we use for building a global basemap at MapBox.

Approaching OSM with an eye for design, one needs to grasp the free-form tagging system. Compelling cartography with this data does not come from building up layers of structured feature-classes,
but instead from experimenting with different pieces, melding them together, and sculpting them into something beautiful.

All the tools we do this with are free and open-source: PostGIS, TileMill, CartoCSS, and a variety of scripting languages, geographic libraries, and helper applications. This talk will go into some of the technical aspects of bringing OSM into these tools, and some of the bleeding-edge features we are using to improve rendering performance and design aesthetics.
