I found OpenStreetMap this morning and noticed the outstanding level of detail in the centre of Turku, a city which tends to be overlooked by other map sites and datasets. It came as a great surprise, then, that on panning down to the Harittu area, I found that the actual road I live on was missing from the map. I grabbed my Garmin eTrex Vista HCx and went out, made a track, uploaded it and made my first contribution to this extremely cool site.
