Slide deck from my presentation at the 2009 State Of The Map Conference on mapping and bicycles. I'd intended to ride from Dunkerque to Amsterdam mapping the route of the LF-1 - a long distance cycle route around the North Sea coast. After just 30 miles disaster struck and disaster struck! I was thrown from my bike after hitting a wet tram line! Fuelled by painkillers and optimism I still rode on for another 60 miles to the town of Veere in Zeeland, Netherlands. At the conference I spoke about hardware required for this type of long distance mapping and the possibilities of 'selection bias' when recording map data dependent upon the mode of transport being used.
