Currently in London my place is Catania, Italy where I mapped the western part of the town. I am mapping everywhere, from Netherlands, (Just a B&B a cheese shop and a bus stop :-D) to Haiti (mapped soon after the earthquake). I am planning to add some details in Uk as well. At the beginning I mapped using a NokiaN95 and Sports tracking recently I bought a new GPS transystem i blue 821 and installed GPSmid on my nokia N95, great combination!
I moved to Ubuntu to develop a thesis on OSM. I still use Windows in another PC.
