The latest outputs from researchers, alumni and friends at the UCL Centre for Advanced Spatial Analysis (CASA).
The eMOTIONAL Cities project has set out to understand how the natural and built environment can shape the feelings and emotions of those who experience it. At its core lies a Spatial Data Infrastructure (SDI) which combines a variety of … Continue reading
Continue reading »Vector tiles have been around for a while and they seem to combine the best of both worlds. They provide design flexibility, something we usually associate to vector data, while enabling fast delivery, like we generally see on raster services. … Continue reading
Continue reading »Anyone working with geospatial data, had probably encountered at some point the need for geocoding. The task of transforming an address (e.g.: a placename, city, postcode) into a pair of coordinates (e.g.: a point geometry) is called forward geocoding, while … Continue reading

My presentation on the “Conference on Advanced Spatial Modelling and Analysis” consisted in some thoughts regarding Big Spatial Data, and how to handle them in terms of modern technologies. It was great to see such a motivated crowd from all … Continue reading →
Recently I had another challenge, which I believe has the characteristics to be a common problem. I have a table with attributes, in CSV format, one of which is geospatial. CSV is a structured format for storing tabular data (text … Continue reading →
Is PostgreSQL/PostGIS suitable for Big Data? This is a question I have been asking myself for a while, and I now have the opportunity to test it with a PostgreSQL instance from Amazon Web Services (AWS); after all, if such … Continue reading →
On a previous post, I expressed my concerns regarding the results of OPTICSxi clustering. Namely, I mentioned an “annoying” spike effect, that turns out massively almost at any simulation (so massively that it is almost a “feature”). A post in … 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 →

The talk was somewhat similar to the one that I gave at the BCS Geospatial SIG. However, I was trying to answer a question that I was asked during […]
