The latest outputs from researchers, alumni and friends at the UCL Centre for Advanced Spatial Analysis (CASA).
Here is the topography slideshow, otherwise read on.. Over the past few years I’ve been looking at lots of relief maps – i.e. those showing geographical topography, specifically land elevation, and I’m generally struck by two things. Firstly how the colour schemes commonly used seem too dominant, which seems to reduce the brain’s capacity for […]

Georeferenced UK statistical data typically comes in one of two spatial coordinate reference systems – either latitude/longitude points based on the World Geodetic System 1984 (‘WGS 84′), or in the eastings/northings system of the British National Grid (based on the 1936 Ordnance Survey Great Britain datum ‘OSGB 36′). The latter system has the benefit of […]

With political transparency an increasingly topical subject in the wake of press scandals and allegations of official coverup, it is a useful exercise to examine any data reflecting the interaction between our leaders and our purveyors of news. Since taking power the UK coalition government has published records of hospitality received by Special Advisers – […]

This may be of use to any R users trying for the first time to get data from sources such as Google Earth or ScribbleMaps into the into webpages. Open the script in text editor first for instructions. Test the finished output in […]

RGL is R’s box of power-tool for 3D object rendering, with functionality for creating 3d mesh objects and curved surfaces, and for using materials and directional lighting. For example the line: plot3d(rnorm(100),rnorm(100),rnorm(100)) creates a 3d scatterplot of […]
