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.

9th-anniversary-london.jpg

A series of London pub meet-ups and mini mapping parties over the summer 2016. 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 mapping the world and releasing it for free! We hope you'll join us! Everyone and anyone is welcome.

Upcoming Events

Tuesday 06 Sep 2016 - Missing Maps/HOT September Mapathon @ Qubit London in London, United Kingdom

If you fancy some Missing Maps Project humanitarian mapping action. SIGN UP FAST





Wed 7th Sept Geomob

On Wednesday 7th September there's #geomob. Presentations of general mappy-geo topics, followed by pub! Topics are not exclusively OpenStreetMap, but talks usually feature a fair bit of OSM goodness, and geomob events are attended by OpenStreetMappers. This time Claire Fram will be talking about doing humanitarian mapping at Arup.

Details on the geomob blog. Sign up on Lanyrd: http://lanyrd.com/2016/geomob-september/




Future events

We'll use this wiki page to announce events, as well as Twitter@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

Summary

OpenStreetMap has usable coverage of London and areas within the M25. The coverage density is not as much as the 208 most densely mapped meta tiles in 2013[1]: however, we have mapped nearly all roads and a lot of other features within the M25.

In the early days, we used Yahoo imagery in addition to GPS tracks to sketch in the features, and then add names from Ordnance Survey data. There are some areas which do not have enough detail from surveys and other open data, but in the early days it was worse, with areas around Hillingdon north of Heathrow glowing red on the NoName map. Today, we can use ITO Map to see where we could do a bit more surveying.

For a long time, we have had complete coverage of the London Underground, allowing us to render a Tube Network Map with small details such as track configurations, tunnels and bridges: our List of London Underground stations gives a raw list of stations as we originally surveyed them through GPS. We also have a strong coverage for stations and lines for DLR, Tramlink, London Overground and National Rail networks, and good coverage of most bus routes in London with the help of NaPTAN.

London also has good coverage of specialised information: Amaroussi has added and maintained Street light information for nearly all classified roads, Welshie has been doing most of the speed limits, while other users are adding lanes, sidewalks, surfaces, trees and even the London Congestion Charge.

Priorities
  1. Mapping London's bus routes will remain a large and ongoing process, because Transport for London frequently alters bus routes to cater for changing demand.
  2. Add the Low Emission Zone.
  3. The public transport scheme is now live, meaning that we will have to update the network: we have to complete the London public transport tagging scheme soon, so that all modes to ensure routing integration and cross-compatibility between the new and old schemes.
  4. Add missing speed cameras and turn restrictions. They are important if OpenStreetMap is going to be a usable backbone for routing devices.
  5. OpenStreetMap is 10 years old this year, and urban regeneration is rendering some areas out of date: for example, the Heygate Estate in Southwark is being demolished and the Alma Estate in Ponders End will follow from next year.

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.
