Can Maths Predict a Riot?

Can Maths Predict a Riot?

Hannah Fry, CASA‘s own Lecturer in the Mathematics of Cities talks through some of the ways in which spatial modelling has the potential to predict major events in cities – in this case rioting. Hannah also has an excellent TEDx talk on the topic of “complexity” which is a field of research that underpins a lot of contemporary research into urban...

Welcome

Welcome

Welcome to the the new look Spatial Analysis blog. My last post was way back in March so I have a lot of catching up to do! The prolonged absence was due to all my energy being spent on completing my PhD thesis in order that I could get it out of the way before starting my new job at the UCL Centre for Advanced Spatial Analysis in London. I will be teaching a module on GI Systems and Science so may share some resources here or be on the lookout for ideas. In addition to the odd teaching resource to add to the growing list of R Spatial resources I hope to continue to upload visualisations of some of the latest freely available datasets and also scour the internet for great work that others have done. I have put a lot of effort into transferring my previous posts and material to the new look blog. If you spot any missing images please let me know. In addition I...

mappinglondon.co.uk: Another Blog about Maps!

mappinglondon.co.uk: Another Blog about Maps!

Followers of spatialanalysis.co.uk will know that a lot of maps I feature are about London. Many of these maps have caught the eye of those outside of the geography, GIS/ spatial analysis community who don’t really have an interest in the technicalities of making the maps etc. Oliver O’Brien and I have decided to team up to launch the mappinglondon.co.uk blog for people who like to see maps of London without the techie blurb/ code you often see here. This is timely as there are some fantastic London mapping events in the pipeline (stay tuned) that I know will spread the good word about the geography and cartography of this great city. The plan is to post little and often so that we can share with you the maps that have been catching our attention. I don’t expect things to change much here, but you may find some lighter cartographic relief over at...

Carto-Junk?

Carto-Junk?

The National Geographic Surname Map has generated a lot of discussion both online and via email. The response has been overwhelmingly positive but some people, unsurprisingly, have suggested improvements. A recent post on the great Junk Charts blog acts as a good summary of the comments I have received. For the purpose of this post I have left out the positives in order that I can address some of the suggested limitations of the map. There is always room for improvement but I thought it would be good to outline some of the logic behind relaxing a couple of Tufte’s classic rules on data visualisation.  I have pasted each suggested improvements from Junk Charts below and added my responses beneath. “They really ought to have used relative popularity rather than absolute popularity. This is another area of improvement for all word clouds. Today, word clouds plot the number of times a specific word appears in a piece of text. We often try to compare several word clouds against each other; and when we do...

Handling Spatial Data with R

Handling Spatial Data with R

Spatial data are becoming increasingly common, as are the tools available in R to process it. It takes a little time to understand how R handles spatial data; this tutorial is designed to help get people started. It outlines how to create a simple spatial points object from as csv file, load and export a shapefile and alter or add spatial projection information. Data and Package Requirements: London Sport Participation Shapefile. Download (requires unzipping). London Cycle Hire Locations: Download. Install the following packages (if you haven’t already done so): maptools, rgdal (Mac users may wish to see here first). Click here to view the tutorial...
