Mapping City Flows as Blood
Blood is everywhere when it comes to describing cities. We have arterial roads, pulsing transport flows, and cities with different metabolisms. Thanks to great new datasets and visualisation software the analogy of cities with pulsing flows is being increasingly utilised for explanatory mapping. For example the work of UCL CASA’s Jon Reades above depicts the London Underground network ...
Pigeon Sim- A fresh way to interact with urban data?
Thanks to an Xbox Kinect, Google Earth and some programming wizardry from UCL CASA researcher George MacKerron it is now possible to fly over London. The video below shows “Pigeon Sim” which has been developed to offer a fresh way of interacting with London’s urban data. Using Peter-Pan like arm gestures (above) users can ...
Sensing the City: Mapping London’s Population Flows
I recently had the pleasure of presenting at the first Data Visualisation London Meetup event where I spoke about some of work we do at UCL CASA. A fair chunk of the slides were movies so I thought it best to stick them in a blog post. If you like what you see you can ...
The Twitter Languages of London
Last year Eric Fischer produced a great map (see below) visualising the language communities of Twitter. The map, perhaps unsurprisingly, closely matches the geographic extents of the world’s major linguistic groups. On seeing these broad patterns I wondered how well they applied to the international communities living in London. The graphic above shows the spatial ...
London Cycle Hire and Pollution
As a cyclist in London you can do your best to avoid left turning buses and dozy pedestrians. One thing you can’t really avoid though is pollution (although I accept cyclists probably aren’t much worse off than pedestrians and drivers in this respect). To illustrate this I have taken data for 3.2 million journeys from ...
Just how far can the Tube take you?
Transport for London have just released their performance data (link here) for the London Underground network. It is in the form of a really detailed file that contains, amongst other things, the “Peak Operated Kilometres” and “Peak Passenger Journeys” for the past 6 years or so. If you total the distances covered by the Tube ...
OpenStreetMap: 5 Years of Mapping London
This week I am giving a talk on some of the London maps that we produce in CASA. The hours of work I put in to such maps is minuscule compared to the amount of effort and time that the OpenStreetMap community have invested in producing a truly open (and often more accurate) map of London (and the ...
The Times Atlas of London
*This post has been cross-posted from the Mapping London blog.* A few months back I had the honour of being asked to approve the use of a couple of excerpts from my London Surname Map in The Times Atlas of London. The wait was finally over last week when I received my copy in the ...
Mapping GCSE Scores
In the UK, August is exam results month for 16-18 year olds. Every year, photos of leaping teenagers clutching their results are accompanied by reports of record attainment rates, debates around how challenging modern exams are and, more so recently than ever, concerns for the number of sixth form and university places. Back in March ...
Mapping London’s Population Change 1801-2030
Buried in the London Datastore are the population estimates for each of the London Boroughs between 2001 – 2030. They predict a declining population for most boroughs with the exception of a few to the east. I was surprised by this general decline and also the numbers involved- I expected larger changes from one year to ...
