We're excited to announce that official Transport for London and National Rail icons will now be featured on Mapbox Streets at rail stations throughout Great Britain.

New icons make neighborhoods more immediately familiar on the already data rich maps, but simplifying the rich OpenStreetMap data required a concerted effort from both our data team and cartographers. In many cases stations are represented as buildings, and other times as a single point. In yet other instances, one station will have multiple points, with each representing a platform or entrance. If two rail networks service the same station, that station might have on point for each rail service.

Many nodes for just two stations - King's Cross and St. Pancras

##An Open Mapping Tool Chain

The process of adding data to OpenStreetMap to styling and publishing your maps online is not obvious at first. I'll walk though the open source tool chain we use to contribute to OSM, and how to use TileMill to leverage OSM data to build custom maps. Specifically I will share some of our recent experience over the past several weeks of tracing in Brazil and publishing maps online. I will share specifics on how to get started tracing roads and buildings from satellite imagery in a few minutes to how we actively engage local communities and working with local governments to open large datasets and import them to OpenStreetMap. Finally I will end showing how how to turn an OSM export into a map and publish it on your web site.
