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 ...
Brilliant Boris Bikes Animation
Some of us at CASA can’t get enough of the Barclay’s Cycle Hire data. We have had Ollie‘s hugely successful flow maps, journey time heat maps, and now the the Sociable Physicist himself, Martin Austwick has created this stunning animation of the bikes. The TFL data release contained the start point, end point, and duration for around ...
Mapping London’s Surnames
Inspired by the What’s in a Surname? map we helped make with the National Geographic, I have created 15 interactive typographic maps to show the most popular surnames across London. What they lack in cartographic brilliance, I hope they make up for in detail. There are 983 geographic units (Middle Super Output Areas) in each map ...
Boris Bikes/Barclays Cycle Hire Average Journey Times
The visualisation above shows the average relative duration of Boris Bikers’ weekday journeys over a 4 month period at hourly intervals. For each time step the average journey time (in seconds) from each docking station has been calculated.This information is interesting because it shows the preference for short journeys around the City of London, whilst ...
The Big Squeeze: London’s Council Funding Cuts
The map is a cartogram showing the level of child poverty for each of London’s councils in addition to their predicted loss in revenue spending power resulting from the recent government cuts. As you can see the shapes of some of the poorest boroughs in London have been enlarged to reflect high levels of child ...
