  • There are .9 Million Shared Bicycles in Beijing

    Recently I become part of the editorial team at the Bike-Sharing World Map (this is a new version, not yet launched) which is the world’s only comprehensive map of bikeshare systems, listing the approximately 2000 active systems along with another 1000 that are either in planning or already closed. The Bike-Sharing World Map was compiled […]

  • Use vs Theft: Risks and Rewards for Dockless Bike Operations in London

    When running a fleet of dockless bikeshare bikes, one of the potentially most costly problems is theft of the bicycles. They aren’t attached to anything if they are dockless, even if they are in a marked “hub”, and, even if the bikes are typically heavier than a personal bike, they can still be easy targets […]

  • FOSS4G UK 2018 Meeting and OpenLayers 4

    I attended and presented at the FOSS4G UK conference in central London, in early March. I was scheduled to present in the cartography track, near the end of the conference, and it ended up being an excellent session, the other speakers being Charley Glynn, digital cartographer extraordinaire from the Ordnance Survey, who talked on “The […]

  • Railway Station Numbers

    You can click on all the images in this blogpost to go explore each view further on the interactive map. The ORR publishes station entry/exit numbers on an annual basis, on a “best guess” basis, using ticket sales, gate information and modelling. The data is split by ticket type – full fare, reduced fare (off-peak […]

  • Eight Ways to Better Flow Maps

    As part of a presentation I gave yesterday at the RSAI-BIS (Regional Science Association International – British & Irish Section) annual conference, on DataShine Travel to Work maps, I outlined the following eight techniques to avoid swamping origin/destination (aka flow) maps with masses of data, typically shown as straight lines between each pair of locations. […]

  • Evolution of London’s Rush Hour Traffic Mix

    My latest London data visualisation crunches an interesting dataset from the Department of Transport (there’s also a London Borough of Southwark version using their local observation data). The data is available across England, although I’ve chosen London in particular because of its more interesting (i.e. not just car dominated) traffic mix. I’ve also focused on […]

  • Lives on the Line v2: Estimated Life Expectancy by Small Areas

    I’ve produced an updated version of a graphic that my colleague Dr James Cheshire created a few years ago, showing how the estimated life expectancy at birth varies throughout the capital, using a geographical tube map to illustrate sometimes dramatic change in a short distance. You can see an interactive version on my tube data […]

  • Big Data Here

    The Consumer Data Research Centre (CDRC) at UCL is organising a short pop-up exhibition on hyperlocal data: Big Data Here. The exhibition is taking place in North Lodge, the small building right beside UCL’s main entrance. The exhibition materials are supplied by the Centre for Advanced Spatial Analysis (CASA). Inside, a big projection shows local […]

  • SIMD 2016: The Scottish Index of Multiple Deprivation

    Like its English counterpart IMD, SIMD is released every few years by the Scottish government, as a dataset which scores and ranks every small statistical area in Scotland according to a number of measures. These are then combined to form an overall rank and measure of deprivation for the area. This can then be mapped […]

  • Tube Heartbeat

    Tube Heartbeat is a interactive map that I recently built as part of a commission by HERE, using the HERE JavaScript API. It visualises a fascinating dataset that TfL makes available sporadically – the RODS (Rolling Origin Destination Survey) – which reveals the movements of people on the London Underground network in amazing detail. The […]
