South Bank/Waterloo OpenStreetMap mapping evening

Help make the map!

OpenStreetMap.org is a not-for-profit collaborative project which originated here in London, with the aim to create a a free map of the world, owned and maintained by local communities.

Volunteers are starting to add lots of finer details to the London map now, and you can help.

On Wednesday evening there's a social meet-up in The Mulberry Bush pub from 8pm, but with some outdoor mapping activity beforehand.
