London is a city in Greater London at latitude 51° 29′ 6″ North, longitude -0° 9′ 0″ West.
London is the capital city of the United Kingdom. Greater London is one of the nine regions of England and is divided into 32 London boroughs. For ceremonial purpose it excludes the City of London. It is the most populous city in Europe (over twice the population of Paris). All road distances to the destination "London" refer to Charing Cross.

A couple of other London events which are related:
- rewiredstate.org events - Hack weekends on various topics, always involving some map maships. Go promote OSM!
- Crisis Camp London used to do monthly meet-ups. Good place for teaching newbies, or doing technical hacking
- http://www.rhok.org/ may also be worth looking into (same idea)
Please use the wiki to pro-actively coordinate the setting up of an "OpenStreetMap presence" at these events... or just go along (Other OSMers may or may not be there)

OSM Coverage
London is still progressing in terms of coverage. Pretty much the entire area within the M25 is mapped out with road coverage, but some of this was sketched in from Yahoo imagery, and now have had their names filled in from Ordnance Survey data. So there are some outlying areas which have never been surveyed and mapped in any detail. We don't have a very clear view of where these area are, but areas around Hillingdon north of Heathrow used to glow red on the NoName map.
For a long time we've had complete coverage of the London underground network allowing us to render a Tube Network Map, including nice details like tunnels and bridges. Our List of London Underground stations gives a plain list of stations as they were originally surveyed by GPS. We have a pretty complete set of stations and rail network for all of the normal surface trains in Greater London, although there may still be some tagging/representation inconsistencies. Bus routes in London are a big task, but this is progressing really well. See the Transport map in London (How's your area?!)
Borough boundaries
The region and administrative area of Greater London is subdivided into 32 London boroughs.
Note that most online maps showing the position of the borders are copyrighted. Even supposedly open licensed maps on wikipedia are actually derived from copyrighted sources. As of February 2013, all the boundaries are mapped from the most accurate source which we can use at the moment - OS Boundary Line data. Ideally we'll keep it clean by surveying signs in the streets. Keep a look out for those "Welcome to London Borough of X" signs while you're out and about.
According to the OS Boundary Line data, the boundary between Southwark and the City of London is roughly the centre-line of the Thames. However the City of London Corporation controls (through Bridge House Estates) the whole of London Bridge so the boundary has been adjusted in OSM to cover the whole bridge. A similar situation exists at Blackfriars Bridge, although this is reflected in the OS data.
Boundaries between the London boroughs have been tagged boundary=administrative and left:district=name right:district=name
The OSM Inspector tool is excellent for checking that a boundary is complete and that all the tagging of the ways and relation is correct. A relation of London Borough Boundary relations is available for reference.
Wikipedia has a rather comprehensive list of boundary changes within London, which links to the relevant governmental orders which made the change. Although many refer to maps not included, the explanatory notes may assist mapping of both the Greater London and borough boundaries.
