Harry Wood's interest in internet collaboration and web2.0 technologies lead him to the OpenStreetMap project three years ago, as a hobbyist mappper, and as an increasingly passionate evangelist, community coordinator and developer. Turning this hobby into a profession, he worked at CloudMade developing core features of the OpenStreetMap website and working on CloudMade products and services which help developers use OpenStreetMap data. In 2010 he plans to operate as a freelance OpenStreetMap consultant http://harrywood.co.uk These slides are (of course) freely re-usable under the Creative Commons Attribution-ShareAlike 2.0 License Map images cc-by-sa2 OpenStreetMap.org contributors.
