OpenStreetMap is an editable map of the whole world, which is being built largely from scratch, and released with an open content license. This event is a social pub gathering. It's open to everyone and anyone, and it's a great chance for people to come along and find out more about OpenStreetMap, chat about ideas for using the maps, or contributing to the maps.
Lots more event details on the OpenStreetMap website
