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.

London mapping evenings 2011 Pimlico.jpg


A series of London pub meet-ups and mini mapping parties over the summer 2014. These events are free and open to all. We normally have a mixture of old OpenStreetMap hands and new people coming along to find out more. The events might include mapping, but mostly we'll just be sitting around in a pub having a friendly chat about little things like freeing the world's geo-data. We hope you'll join us! Everyone and anyone is welcome.

Upcoming Events

Next OSM meet-up

Two mapping events in a row. Phew! Next one will be a plain old pub meet-up. Late April some time

DETAILS TO BE DECIDED

(Sat-Sun April 26th 27th April: non-osm hack)

http://hackathoncentral.com - Big general hackathon event. Not directly map related but there's sure to be people using maps for their hacks.

Sat 9th August: OSM's 10th Birthday Party

OpenStreetMap 10th Anniversary Birthday party. Worldwide party! We'll do something in London. Nothing has been decided yet, except the date. Keep it free!

8th - 10th Aug Wikimania London

Wikimania, the annual international conference of wikipedia (and wikimedia projects) is coming to London this year.

Wikimania London 8th - 10th Aug plus various fringe events.

We can plan an OpenStreetMap presence on our Wikimania 2014 London page. Two sessions where submitted: OpenStreetMap mapping party and OpenStreetMap mapping workshop. You can already indicate your interest in these sessions (which may help them get accepted!)

The conference is over the same weekend as the OSM birthday party. A clash with possible upsides.


Future events

We'll use this wiki page to announce events, as well as Twitter bird.svg @OSMLondon . Announcements may come at short notice!

There’s lots of other events in London e.g. tech meet-up groups, for which OpenStreetMap is relevant. 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)

We’ve got a list of London event venues for future events of a non-pub format. Please add to that if you have ideas or if your organisation would like to host or sponsor an event!

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?!)

London Boroughs

London is subdivided into 32 boroughs. Within our data we see these represented as admin boundaries, which are now all mapped out. See London borough boundaries for details and links to these.

London boroughs are also UK local councils of course, and with all of these it would be fantastic to see them making use of open geodata from OpenStreetMap, working with our community to supply change updates, or partnering with us to engage local communities via the process of OpenStreetMapping.

We could create wiki pages about the London boroughs.

Barking and Dagenham, Barnet, Bexley, Brent, Bromley, Camden, Croydon, Ealing, Enfield, Greenwich, Hackney, Hammersmith and Fulham, Haringey, Harrow, Havering, Hillingdon, Hounslow, Islington, Kensington and Chelsea, Kingston upon Thames, Lambeth, Lewisham, City of London, Merton, Newham, Redbridge, Richmond upon Thames, Southwark, Sutton, Tower Hamlets, Waltham Forest, Wandsworth, Westminster

…but note that wiki pages about small areas can fall into disuse quite easily, so don’t be too ambitious with info requiring updates. The London boroughs might be a useful subdivision for tracking mapping progress, but probably not through manual updating of wiki pages. One automated tool which uses the subdivision to good effect already is the OSM and OSL differences analysis e.g. see the report for Camden

Out-of-copyright maps of London

There are some Out-of-copyright maps which feature London at low details levels. The most detailed is Richard's scans of the 1933/34 ABC Street Atlas of London (Torrent) (Alternative). Back in the early days (2007) we were able to try and use these to fill in some London details, or at least help us not get lost while we mapped London ourselves! These days there's nothing we can learn from them which isn't already better mapped in OpenStreetMap.
