I came, I saw, I mapped.
I've been mapping since early 2007, when I first got my GPS.
The first place I mapped was a few streets in Greenwich, UK -- longitude 0°00'00" was an appropriate place to start my mapping efforts. Since then, I've mapped many places around the world, including a large part of the western suburbs of Brisbane, Queensland, Australia.
Some of the countries where I've done some mapping include: Hong Kong, Macau, China, New Zealand, Morocco, UK and the US.
