On Sunday afternoon, at lunch time, there will be an OpenStreetMap mapping party.

We will do a brief excursion outside, nearby the venue to collect some data, using field papers (pen and paper / notes) and mobile apps (if you have a gps-enable device).
We will then spend some time to enter the data into OSM, while eating lunch.
No experience is necessary to participate and all are welcome.
Cheers, Katie
