London Underground geographic maps

A series of geographic maps of the London Underground in the LU house-style have been made by ed g2stalk and James F.. These images are based solely on GPS data, which is in the public domain, and they are available under the GFDL.

[edit] Creation process

A PHP script processes the line definitions to create list of stations on the line, calculates coordinates of the control points for bézier_curve, and then outputs the graphic as an SVG file. The SVG files are then fine tuned in an SVG editor (text placement, mostly) and rendered as PNGs.

[edit] To do

Bakerloo
  • Correct the spelling of "Harrow & Wealdstone" on the map.
  • Extend to Watford (when planned extension occurs at currently unspecified date)
  • At Edgware Road, the Bakerloo Line station is to the north of the station serving the Circle, District, and Hammersmith & City lines. The map shows it as being south of the Circle line station.
  • Move Willesden Junction to zone 2/3
Metropolitan
  • Separate the Jubilee and Met lines between Finchley Road and Wembley Park on the combination map as the Met Line doesn't serve the intermediate stations.
Northern
  • Create map including extensions from new works programme and Sutton extension?
Piccadilly
  • Line changes - Heathrow T5, East London Line extension (and current closure of Shoreditch), DLR extension(s).
Waterloo & City
DLR
  • Add Langdon Park
  • Add Woolwich Arsenal
Other lines
General design
  • Integrate with Google Maps
  • Suggest adding M25 to "London Underground Full map" to improve context. Also to demonstrate inherent northernwards bias of tube line distribution.
  • Add mid-station control points - i.e., Piccadilly line should bend sharply twice between Knightsbridge and South Kensington, the Jubilee line takes a significant eastward curve between Baker Street and Bond Street, and the Northern and Bakerloo lines don't actually share track as they cross the river. The 'find location' map browser of the journey planner on the TFL website shows the undergound line routes as dotted lines (http://journeyplanner.tfl.gov.uk/)
  • Put station markers where the platforms are rather than the surface entrances? There are big differences for some stations. The maps could show platform locations, with little blobs-on-sticks showing the asscoiated entrance(s).
  • Perhaps include closed lines in overall map, represented by semi-transparent lines.

[edit] Source data

The source data is available as an SQL dump, as a CSV file, and as readable HTML tables.

[edit] Source code

Here is the script used to generate the rough maps. It generates Bezier curves that smoothly fit the points, and station markers on both sides (when not a dot), so each map will require a manual clean-up.
