State of the Map US is the largest gathering of OpenStreetMap and open mapping community members from across the country. This year we’re celebrating our public lands with the theme “The Great Outdoors” (though you can expect many other topics too!) There will be two days of talks and workshops, and three nights of social events. Come connect with other 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 data, and hack on the latest open source tools.
