The latest outputs from researchers, alumni and friends at the UCL Centre for Advanced Spatial Analysis (CASA).
The maps above were created for an article in The Conversation entitled Next slide please: data visualisation expert on what’s wrong with the UK government’s coronavirus charts in it I argue that there needs to be better data visualisations in government briefings. I give a particular example about how maps can appear differently depending on the…

Ecologists deploy point pattern analysis to establish the “home range” of a particular animal based […]

It has been a long held dream of mine to create a spinning globe using nothing but R (I wish I was joking, but I’m not). Thanks to the brilliant mapmate package created by Matt Leonawicz and shed loads of computing power, today that dream became a reality. The globe below took 19 hours and 30 […]

The authors (Meredith Reba, Femke Reitsma & Karen Seto) write: How were cities distributed globally in the past? How many people lived in these cities? How did cities influence their local and regional […]

The data have been obtained from the CLIWOC project and they represent a sample of digitised ships’ logs from the 18th Century. We are using a very small […]

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 …
