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 →

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 →

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 →

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 →
