The latest outputs from researchers, alumni and friends at the UCL Centre for Advanced Spatial Analysis (CASA).
Jason Dykes showed this at the GeoVisualisation Meeting in Oxford on August 30th: A map of road crashes in Great Britain (not the UK) from 1999 to 2010. It mirrors of course the road network and the density of population but it is a remarkable graphic. It was made by the BBC and first published […]
Continue reading »After giving up on Gephi (again, I really should learn), I decided it was time to get to grips with Python and iGraph since I really need to produce multiple iterations of a graph. The matmos at CASA have, of course, been touting Python for ages, but I’ve just not had the time/incentive to install […]
Continue reading »As I get to better grips with the full richness of the Oyster data set and the complexity of the TfL network it’s gradually getting easier to build better visualisations. One of the ones that I’ve wanted to revisit for quite some time was my original ‘pulse of the city’ animation (you can see it […]
Continue reading »I’ve been meaning to post this for ages but have had a great deal on my plate (more posts and visualisations to follow in the next week I hope) so this has kept slipping, together with the six or seven other ‘draft’ posts I’ve got going. Anyway, this visualisation shows average entries at each and every Underground, […]
Continue reading »Full Details of the Meeting are Here Various people from UCL and Kings are contributing to this meeting in Berlin. Mike Batty from CASA is talking on how cities and their evident complexity require big data which is rapidly becoming available, Phil Treleavan from CS at UCL is talking about experimental computational finance in […]
Continue reading »The Royal Netherlands Academy of Arts and Sciences (KNAW) and the Netherlands Organisation for Scientific Research (NWO) are organising this seminar on 5th March 2012 starting at 9-30am at Trippenhuis, Kloveniersburgwal 29, the Netherlands. Mike Batty is talking about Complexity in Cities: Are Cities Becoming More and More Complex?, Martin Novak is talking about […]
Continue reading »Satellite Meeting: Complexity in Spatial Dynamics (COSMIC) Location: Brussels, 5th of September 2012 Organizers: Peter Nijkamp, Michael Batty, Stewart Fotheringham, and Emmanouil Tranos Background New bottom up, digital data collected for entire populations, has started being utilised in urban science …
Continue reading »In one of the more unusual invitations that I’ve received over the past few years, I was asked to speak about visualisation and open data at Transport Ticketing 2012, currently happening down in South Ken. Interestingly, in spite of …
Continue reading »One of the objectives of the COSMIC project is to “extend our current techniques of visualising complex spatial systems… [to] enable a wide range of stakeholders to be involved both in understanding such complexity and using it in policy analysis.” Normally, …
Continue reading »The flow analogy is central to our work in COSMIC, Mechanicity and related projects which argue that cities should be considered as first and foremost as flow systems, not as locational patterns. This is massive break with the past as …
Continue reading »Inspired by Jon Reades’ great visualizations of flows using the TfL Oyster card data, we are now starting to examine the statistical properties of the data, beginning with an analysis of what goes on in the nodes. The data yields …
Continue reading »I’ve been working with the TfL data over the past few weeks to better understand the geographical distribution of journeys and how this affects the load on individual segments across the transport network. In other words, we all know that …
Continue reading »Perhaps it’s careless wording by the Wall Street Journal, but Eric Van der Kleij appears to be claiming that: The number of start ups in the U.K.’s Tech City has more than doubled since the government-led initiative was launched last …
Continue reading »In my work on social networks, one thing that has been of particular interest to me is the way that social network structure seems to be correlated with access to opportunity — both for individuals, and (though I think this …
Continue reading »As many of you know, for quite some time I’ve been wrestling with a massive data set from TfL — I make it that I have 120 million trip segments across 88 million identifiable journeys in the course of just …
Continue reading »Historically, the downtown of major cities is where the most highly-skilled and highly-remunerated work was done — think: Wall Street, the City, etc. But as space has run out in the core, secondary centres such as Canary Wharf and La …

Continue reading »In fits and starts, over the past month I’ve been getting to grips with an exciting new Oyster Card data set from TfL and the wonderfully supportive Andrew Gaitskell, their resident Oyster Card data expert. For those few of you …
Continue reading »COSMIC (COmplexity in Spatial dynaMICs) is a proposal linking three research groups (Vrie University (VU) Amsterdam, UCL and National University of Ireland at Maynooth (NUIM)) dealing with urban science and geo-spatial analysis. The network will focus on urban dynamic processes …
