Eight Ways to Better Flow Maps

As part of a presentation I gave yesterday at the RSAI-BIS (Regional Science Association International – British & Irish Section) annual conference on DataShine Travel to Work maps, I outlined the following eight techniques to avoid swamping origin/destination (aka flow) maps with masses of data, typically shown as straight lines between each pair of locations. … Continue reading Eight Ways to Better Flow Maps

Evolution of London’s Rush Hour Traffic Mix

My latest London data visualisation crunches an interesting dataset from the Department of Transport. The data is available across England, although I’ve chosen London in particular because of its more interesting (i.e. not just car dominated) traffic mix. I’ve also focused on just the data for 8am to 9am, to examine the height of the … Continue reading Evolution of London’s Rush Hour Traffic Mix

Lives on the Line v2: Estimated Life Expectancy by Small Areas

I’ve produced an updated version of a graphic that my colleague Dr James Cheshire created a few years ago, showing how the estimated life expectancy at birth various throughout the capital, using a geographical tube map to illustrate the sometimes short-distance changes. You can see an interactive version on my tube data visualisation platform. Click … Continue reading Lives on the Line v2: Estimated Life Expectancy by Small Areas

Big Data Here

The Consumer Data Research Centre (CDRC) at UCL is organising a short pop-up exhibition on hyperlocal data: Big Data Here. The exhibition is taking place in North Lodge, the small building right beside UCL’s main entrance. The exhibition materials are supplied by the Centre for Advanced Spatial Analysis (CASA). Inside, a big projection shows local … Continue reading Big Data Here

SIMD 2016: The Scottish Index of Multiple Deprivation

Like its English counterpart IMD, SIMD is released every few years by the Scottish government, as a dataset which scores and ranks every small statistical area in Scotland according to a number of measures. These are then combined to form an overall rank and measure of deprivation for the area. This can then be mapped … Continue reading SIMD 2016: The Scottish Index of Multiple Deprivation

Putting Cartography Back on the Map – Google Maps Getting Prettier

There was a time when Google Maps was an ugly ducking. It started life as a road map, and its grey background was decryed at a memorable keynote at the British Cartographic Society annual conference 8 years, contrasting with the classic Ordnance Survey Landranger maps where the spaces between roads were normally full of “something” … Continue reading Putting Cartography Back on the Map – Google Maps Getting Prettier

Changes in Deprivation in England, 2010-15

I’ve just now published a number of maps on the CDRC Maps platform which uses the DataShine mapping style (more about DataShine) to show demographic data relating to consumer and other datasets. The maps relate to the Indices of Deprivation 2015, small-areas measure of deprivation in England, which were compiled and published at the end … Continue reading Changes in Deprivation in England, 2010-15

Living Somewhere Nice, Cheap and Close In – Pick Two!

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!

Tube Line Closure Map

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

Street Trees of Southwark

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

Election Time!

I’ve created an Election 2015 Time Map which maps the estimated declaration times that the Press Association have published. It follows on from a similar map of the Scottish independence referendum. Each constituency is represented by a circle which is roughly in its centre (using a longest-interior-vertex centroid determined in QGIS). The area of the … Continue reading Election Time!

Ordnance Survey Open Data – The Next Level of Detail

An encouraging announcement from BIS (the Department for Business, Innovation and Skills) a few days ago regarding future Open Data products from the Ordnance Survey (press release here) and the Ordnance Survey – two pieces of good news: The OS will be launching a new, detailed set of vector data as Open Data at the … Continue reading Ordnance Survey Open Data – The Next Level of Detail

Tube Tongues

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 […]

A Changing City – OS Open Data Reveals a Dynamic London

Since launching the data store in early 2010, the Ordnance Survey have been releasing a number of updates to an interesting dataset – VectorMap District – which is a generalisation and simplification of their MasterMap “gold standard” dataset for Great Britain. The updates have been appearing roughly every 6-12 months, and by comparing them in […]
