The latest outputs from researchers, alumni and friends at the UCL Centre for Advanced Spatial Analysis (CASA).
The Tube Line Closure Map accesses Transport for London’s REST API for line disruption information (both live and planned) and uses the information there to animate a geographical vector map of the network, showing closed sections as lines flashing dots, with solid lines for unaffected parts. The idea is similar to TfL’s official disruption map, … Continue reading Tube Line Closure Map →
Continue reading »Earlier this month, I gave a short presentation at the Big Data and Urban Informatics Workshop, which took place at UIC (University of Illinois in Chicago). My presentation was an abridged version of a paper that I prepared for the workshop. In due course, I plan to publish the full paper, possibly as a CASA […]

At CASA we’ve always been keen on marrying the online with the tangible – such as the London Data Table (a real table, cut in the shape of London, showing live London data), PigeonSim (fly around a Google Earth view augmented with real-time information) and a couple of 3D printers, one of which was used […]

It’s always irked me slightly that many online maps of London show the various tube services as straight lines between stations, or as idealised Bezier curves. Perhaps the regimented lines and angles of the official “Beck-style” tube diagram has meant that, when translating into a “real life” geographical map, people have tended to keep the […]

The above interactive map compares the popularity of different CitiBike docking stations in New York City, based on the number of journeys that start/end at each dock. The top 100 busiest ones are shown in red, with the top 20 emphasised with pins. Similarly, the 100/20 least popular ones are shown in blue*. CitiBike is […]

CASA colleague Steven James Gray used the API from CityDashboard, which I created early last year by aggregating various free London-centric data feeds into a single webpage, to power the data for a 4×3 array of iPads, mounted in a wooden panel, itself iPad-esque in shape. The “iPad wall” was mounted in the Mayor of […]

I’ve fixed and tidied up a visualisation I created back in 2010, which showed the results of that year’s General Election in the UK. Newer versions of OpenLayers had broken it (specifically the use of addUniqueValueRule with a custom context resulted in no circles appearing) and also the UI looked rather rudimentary. Now it has […]

I’ve made some minor alterations to the CSV API for CityDashboard. The main changes are in the metadata rows (the top two) rather than the subsequent rows. Specifically, the top metadata row has now split out the description, source and … Continue reading →

I pulled together this interactive map of Proposed Constituency Boundary Changes in England, after the information was released by the Boundary Commission for England last week. My colleague James Cheshire highlighted that this kind of map could be illuminating, particularly … Continue reading →
