June 6–8, 2024
OpenStreetMap US hosted the 12th annual State of the Map US conference along the Wasatch Front in Salt Lake City, Utah.
The Best Party in Mapping
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.
Whether you’re brand new to open mapping or you’re an OpenStreetMap veteran, State of the Map US is for you. We’re excited to see you in Utah.
See our logistics page for lodging deals, transport information, and the conference map.
