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

Broadband Speed in the UK

I’ve recently a published on CDRC Maps a map of Broadband Speed in the UK. This is the average download speed for residential properties, right across the UK. It’s based on data annually released by OFCOM (I’m using the most recent dataset from 2016). I’m using a Purple-White-Green colour ramp, where Purple indicates areas with … Continue reading Broadband Speed in the UK

Panama’s Population Geographies

Panama is a Central American country with around 4 million population. The country is split into 10 provinces (including one that was split from another in 2014). The population is obliged to register for and obtain an ID card, or “cedula” which contains an interesting attribute. The prefix of their ID number indicates their province … Continue reading Panama’s Population Geographies

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 Code

So Big Data Here, a little pop-up exhibition of hyperlocal data, has just closed, having run continuously from Tuesday evening to this morning, as part of Big Data Week. We had many people peering through the windows of the characterful North Lodge building beside UCL’s main entrance on Gower Street, particularly during the evening rush … Continue reading Big Data Here: The Code

Busiest Tube Station Times

Here are the busiest tube station quarter-hour periods, based on the Transport for London 2015 RODS data (modelled, based on typical autumn weekday), used in TubeHeartbeat, adding together entries, exits and interchange stats and excluding Kensington Olympia. The main pattern shows that stations further out from London’s main work areas (The West End, the City … Continue reading Busiest Tube Station Times

Mapping at the Edge – the BCS/SoC Conference 2016

The British Cartography Society and Society of Cartographers* once again combined their two annual conferences together, for a two-day meet in Cheltenham in early September. After last year’s win for the DataShine website, I was there in a more passive capability, although my colleague Dr Cheshire, who collected a trio of prizes last year, presented … Continue reading Mapping at the Edge – the BCS/SoC Conference 2016

Population Density and Urban/Rural Split of the UK

A new map on CDRC Maps showing perhaps one of the simplest demographic metrics – residential population density – how many people live in each hectare across the UK. The data is available at the smallest statistical area available (output areas in GB and small areas in NI) and I have combined this with the … Continue reading Population Density and Urban/Rural Split of the UK

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

Behind the Code in TubeHeartbeat

As a follow-up to my intro post about TubeHeartbeat, here’s some notes on the API usage that allowed me to get the digital cartography right, and build out the interactive visualisation I wanted to. The key technology behind the visualisation is the HERE JavaScript API. This not only displays the background HERE map tiles and … Continue reading Behind the Code in TubeHeartbeat

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

Population Change in Great Britain 2011-14

The ONS publish small-area population estimates annually, for England and Wales, and the NRS similarly do for Scotland. By taking two of these datasets, we can see how the population of Great Britain is changing – births, deaths, internal and international migration and military deployments/homecomings all act to fluctuate the population. I’ve taken the 2011 … Continue reading Population Change in Great Britain 2011-14

Working Nation

Top Industry maps the most popular employment for each of the ~220000 statistical small areas* within the UK. I’ve reused the “top result” technique that has produced interesting maps for travel to work, to look at the Industry of Employment tables produced by the national statistics agencies, from the 2011 Census. The tables I’ve used … Continue reading Working Nation

The Age of Buildings

We don’t have open individual building age data in the UK, unlike in some other countries (the data has been used to great effect in New York City and Amsterdam) but the Valuation Office Agency, which amongst other things decides council tax bandings for residential properties in England and Wales, has published some interesting data … Continue reading The Age of Buildings

London’s Bikeshare Needs A Redistribution of Stations

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
