The OpenStreetMap project has over half a million map contributors and a fairly extensive developer community. This past weekend, the first-ever OpenStreetMap hack weekend was held in Toronto, Canada (second-ever North American hack) at Ryerson University. This event was jointly hosted with the Department of Geography, Master of Spatial Analysis and the Student Association of Geographic Analysis. Event coördination was taken care of by Richard Weait, long-time advocate of OpenStreetMap.
