OpenStreetMap is a project to produce an open map of the world, that anyone can edit.
This is a one-day (or half-day, if you prefer) mapping party. We'll do some mapping in the morning, meet for lunch at a pub, do some more mapping and then slake our thirst in another pub. The aim is to name all the unnamed roads, verify the geometry and collect points of interest.
We are also interested in meeting new people who want to find out more about OpenStreetMap. Feel free to come along! If you are new to mapping, but want to give it a try, you might perhaps get one of us to give you a little mapping demonstration. You'll need to get in touch and arrange to meet us somewhere (e.g. the tube station) before we meet in the pub later. Alternatively read the Map Making Overview, and just give it a go! Note that you don't need a GPS unit, although if you have one, this is a fun way to put it to good use. Either way, you'll want a printout of the area you're planning to map, since London already has many street layouts sketched in (without names). Alternatively you're very welcome to just join us later in the pub.
