The latest outputs from researchers, alumni and friends at the UCL Centre for Advanced Spatial Analysis (CASA).
*Cross-posted from London: The Information Capital’s website* London’s maps are special. They were drawn by pioneers such as Charles Booth, who revealed the full extent of the city’s poverty, Jon Snow, who deployed maps to determine the cause of cholera, and Phyllis Pearsall, who mapped 23,000 streets in her hugely popular ‘A to Z’ guide. […]

The topic was current CASA research from the RESOLUTION project, looking at developing fast and consistent methods of measuring public transport accessibility between different … Continue reading Open Source Public Transport Accessibility Modelling →
TubeHeartbeat is a interactive map that I recently built as part of a commission by HERE, using the HERE JavaScript API. It visualises a fascinating dataset that TfL makes available sporadically – the RODS (Rolling Origin Destination Survey) – which reveals the movements of people on the London Underground network in amazing detail. The data … Continue reading TubeHeartbeat →
Continue reading »High rise developments are often exclusive private spaces, as attested by the current glut of luxury flats, hotels and offices rising across Inner London. Even recent developments advertising their public space credentials have come up short, with for example the Shard’s fantastic views costing £25 entry fee, or the Walkie-Talkie’s ‘skygarden’ amounting to an expensive restaurant and some pot plants. … Continue reading Tate Modern Switch House: a New Perspective on London →
London boasts over 300 different spoken languages – more than any other city in the world. The capital’s lingua franca, of course, remains English: 78% of Londoners cited it as their ‘main’ language in the 2011 Census. The other 22% speak in different tongues, including Urdu, Somali and Tagalog. This map from London: The Information Capital celebrates […]

The London Panopticon utilises the traffic camera feed from the TfL API, which recently added 10-second-long video clips from the traffic cameras on TfL “red route” roads, to show the current state of traffic near you. It loads the latest videos from the nearest camera in each compass direction to you. The images are nearly-live … Continue reading London Panopticon →

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 […]

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 […]
