The latest outputs from researchers, alumni and friends at the UCL Centre for Advanced Spatial Analysis (CASA).
Here’s an interesting graph, which combines data on total journeys per day on London’s bicycle sharing system (currently called “Santander Cycles”) from the London Data Store, with counts of available bicycles per day to hire, from my own research database. The system launched in summer 2010 and I started tracking the numbers almost from the … Continue reading London’s Bikeshare Needs A Redistribution of Stations →

Mapping for Change, the social enterprise that I co-founded, has been assisting community groups to run air quality studies for the past 5 years. During this period we have worked in 30 communities across London, carrying out studies with different tools – from collecting leaves, to examining lichens, to using diffusion tubes. We have also followed … Continue reading New Citizen Science for air quality campaign

When people decide to move to London, one very simple model of desired location might be to work out how important staying somewhere nice, cheap, and well located for the centre of the city is – and the relative importance of these three factors. Unfortunately, like most places, you can’t get all three of these … Continue reading Living Somewhere Nice, Cheap and Close In – Pick Two! →

OpenStreetMap is still surprisingly incomplete when it comes to showing buildings for the London area, this is a real contrast to other places (e.g. Birmingham, New York City, Paris) when it comes to completeness of buildings, this is despite some good datasets (e.g Ordnance Survey OpenMap Local) including building outlines. It’s one reason why I … Continue reading OpenStreetMap: London Building Coverage →

Here’s a graphic I’ve made by taking a number of screenshots of DataShine Commute graphics, showing the different methods of travelling to work in the City of London, that is, the Square Mile area at the heart of London where hundreds of thousands and financial and other employees work. All the maps are to the … Continue reading The City of London Commute →

The Tube Line Closure Map accesses Transport for London’s REST API for line disruption information (both live and planned) and uses the information there to animate a geographical vector map of the network, showing closed sections as lines flashing dots, with solid lines for unaffected parts. The idea is similar to TfL’s official disruption map, … Continue reading Tube Line Closure Map →

Above is an excerpt of a large, coloured-dot based graphic showing the locations of street trees in Rotherhithe, part of the London Borough of Southwark in London, as released by them to the OpenStreetMap database back in 2010. You can download the full version (12MB PDF). Street trees are trees on public land managed by … Continue reading Street Trees of Southwark →

Stations on the tube map with multiple lines are normally shown with a white circle (except where obscured by a disabled access blob) indicating connections where you can change lines there, while continuing on a single journey (and so not have to pay for two). However, there are a number of connections not shown on … Continue reading Out of Station Interchanges (OSIs) →

A friend forwarded me this article which discusses this paper by researchers at the Yahoo Labs offices in Barcelona and the University of Turin. The basic idea is that they crowdsourced prettiness of places in central London, via either/or pairs photographs, to build up a field of attractiveness, then adjusted a router based on this … Continue reading Taking the Scenic Route – Quantitatively? →

I’ll be gradually tweaking this article to add/amend sources, clarifications and develop some of my arguments. A big announcement for the “Boris Bikes” today, aka Barclays Cycle Hire. London’s bikeshare system, the second largest in the western world after Paris’s Velib and nearly five years old, will be rebranded as Santander Cycles, and the bikes … Continue reading Seeing Red: 15 Ways the Boris Bikes of London Could be Better →

How many of London’s 32 boroughs (& the City of London) would you pass through on a single end-to-end journey on the tube? It turns out that if you travel the length of the Piccadilly Line (Uxbridge branch), then, in a single journey, you’ll pass through 14 boroughs and stop at all of them but … Continue reading London Boroughs and Tube Lines →

As a weekend project, I’ve made an interactive version of my London North/South artwork. As well as the blue and red house silhouettes, assembled in QGIS, I’ve added in GeoJSON files of the River Thames (from Ordnance Survey Vector Map District, like the buildings) and of tube/DLR/Overground stations – the location/name/network data is from this […]

The LuminoCity3D site maps domestic energy use in England and Wales at 1km2 scale using data from DECC. This map has also just been published as a featured graphic in Regional Studies Regional Science.…

Cross-posted from Mapping London, edited slightly. This is a map of geolocated Tweets for the whole world – I’ve zoomed into London here. The map was created by Eric Fischer of Mapbox, who collected the tweets over several years. The place where each tweet is posted from is shown by a green dot. There are […]

This book, which features great examples of London building architecture, is itself distinctively designed and immaculately presented. It’s been out for a couple of years now, however I was recommended it when purchasing another book recently on Amazon, as an impulse purchase, it’s an excellent find. The book was authored by Hannah Dipper and Robin […]

I contributed a number of graphics to LONDON: The Information Capital, a book co-written by Dr James Cheshire, also of UCL Geography. Two of my graphics that made it into the book were based on data from OpenStreetMap, a huge dataset of spatial data throughout the world. This first graphic forms one of the chapter […]

If you are a Londoner but felt that Tube Tongues passed you by, maybe because you live in south-east London or another part of the city that doesn’t have a tube station nearby, then here’s a special version of Tube Tongues for you. Like the original, it maps the most popularly spoken language after English […]

Median house prices are at £300k (8 times median household income) while average prices have passed half a million. London is now amongst the most expensive cities in the world, a situation with severe consequences for economic competitiveness and…

As a followup to Tube Tongues I’ve published Working Lines which is exactly the same concept, except it looks at the occupation statistics from the 2011 census, and shows the most popular occupation by tube station. Again, lots of spatial clustering of results, and some interesting trends come out – for example, the prevalence of […]

I’ve extended my map of tube journeys and busy stations (previous article here) to add in an interesting metric from the 2011 census – that of the second most commonly spoken language (after English) that people who live nearby speak. To do this I’ve analysed all “output areas” which wholly or partly lie within 200m […]

The above graphic (click for full version) shows 12.4 million bicycle journeys taken on the Barclays Cycle Hire system in London over seven months, from 13 December 2013, when the south-west expansion to Putney and Hammersmith went live, until 19 July 2014 – the latest journey data available from Transport for London’s Open Data portal. It’s an update of a […]

The Diamond Geezer is, this month, climbing the highest tops in each one of London’s 33 boroughs. To find the highest points, he’s used a number of websites which list the places. These derive the data from contour lines, perhaps supplemented with GPS or other measurements. However, another interesting – and new – datasource for […]
