Miguel Leonardo has produced a map showing the results of a project with Francisco Rowe and Niall Newsham clustering the trajectories of population decline in Spain.
Sian Teesdale has mapped transport infrastructure in California, using Natural Earth data.
Maya Middleton-Welch, one of our newest Data CDT PhD students, has mapped residential population in Liverpool using QGIS, a GIS software Maya has only been introduced to this term.
Mark Green introduces 'post-it note' mapping to visualise the GPS trail for Tucker*, the GDSL cat, during November (*Tucker is a house cat).
Urban and rural doesn't need to be binary. Dani Arribas-Bel and Martin Fleischmann introduce the Spatial Signatures as a more nuanced way to look at the landscape w/ urban lenses. Wanna know more? Watch the youtube video.
Nikos Patias maps the Sustainable Urban Development Index that aims to promote sustainable urban land use and improve neighbourhood social cohesion. Find out more here.
Olivia Horsefield maps global pirate attacks from 1993 to 2020 sorted by attack type. Data available here. Explore the gif here.
Jamie O'Brien's space syntax analysis of Merseyside's road network reveals areas of high integration, formatted with darker lines. This helps to show how city regions are, in some ways, like archipelagoes. They are held together by underlying infrastructures, but their communities live within discete sub-networks.
Francisco Rowe explores digital traces on human mobility flows from mobile phone data in Barcelona, Spain and the 15-minute city concept. Paper is open access and available here. Code available here.
James Murphy has created a DEM of Yosemite Valley, California at 10m resolution, overlayed with Sentinel-2 RGB imagery using the rayshader package, instructions here. Explore the gif here.
Andrea Nasuto has created maps showing the extent to which boundaries derived from 1 month mobility data in New York (General) change over time (yellow areas). Code available here. To know more about how to derive boundaries from mobility data see here.
Jeremiah Nieves created an animated time-series of Europe and African proportional settlement growth (globally rescaled) from 2000-2015 at a 1km resolution. See the animated map at here.
Jacob Macdonald is exploring which of Englands retail centres come out on top with their local historic amenities. Feel like taking a trip back in time on your day out at the shops? Made using some great data from Historic England and CDRC.
Alex Singleton maps the Internet User Classification on the new CDRC mapmaker platform. Explore the map here.
Francisco Rowe maps the spatial patterns of internal migration during the pandemic revealing that northern major cities of England gained population through internal migration.
Cait Robinson has created a map of average July temperatures in the UK for a high emissions scenario, based on the Met Office UKCP18 climate projections. Find the code here.
Danial Owen visualises the extent of our vision if the earth were flat.
Patrick Ballantyne has mapped towns called Malice at the Local Authority District level across Great Britain, as an ode to the legendary song by The Jam.
Francisco Rowe mapped changes in energy use during the early stages of COVID-19 globally using night-time satellite imagery. Joint work Cait Robinson and Nikos Patias. See here.
