We have had Mapchester, but there is still plenty of mapping to do. There will be a second Manchester mapping party, sponsored by CloudMade, running across the weekend of Saturday 25th and Sunday 26th October.
OpenStreetMap is a free editable map of the whole world. It is made by people like you. OpenStreetMap allows you to view, edit and use geographical data in a collaborative way from anywhere on Earth.
