The latest outputs from researchers, alumni and friends at the UCL Centre for Advanced Spatial Analysis (CASA).
In the recently released “Handbook of Spatial Analysis in the Social Sciences” edited by Sergio Rey and Rachel Franklin, we (Alison Heppenstall, Ed Manley, Nicolas Malleson and myself) have a chapter entitled “Simulating Geographical Systems using Cell…

Inspired by @jeroenhjanssens, author of the Data Science Toolbox, I decided to give a go to one of the most unfriendly data sources: An XML API. Apart from its rich syntax with query capabilities, I tend think XML is highly … Continue reading →
Recently I have been looking into different algorithms for the clustering geospatial data. The problem of finding “similar” regions in space, is a very interesting one, since this type of classification enables a whole range of applications (e.g.: urban development, … Continue reading →
