Workshops on the 7th, the main conference on the 8th and 9th, and a hack day on the 10th. The State of the Map conferences are always a lot of fun and a great chance to meet other OSMers. Visit http://stateofthemap.us/ for more info.
This group is about growing the OpenStreetMap community here in the Bay Area. Our events are open to everyone, from open source enthusiasts, cyclists, GIS professionals, geocachers, and beyond. Anyone and everyone who is interested in maps, map making and free map data is welcome to join our group as well as attend our events.
