The Mappiest Event of the Year

Now in its 15th year, State of the Map US is the largest gathering of OpenStreetMap community members from across the country. (It’s also the best party in mapping!)

Come connect with mappers, businesses, academics, government agencies, and nonprofits, all collaborating around the free and editable map of the world. Share your vision for the project, learn how to work with OpenStreetMap, and hack on the latest open source tools.

Whether you’re brand new to open mapping or you’re an OpenStreetMap veteran, this conference is for you. We’re excited to see you in Boston.
