Mapping City Flows as Blood

Blood is everywhere when it comes to describing cities. We have arterial roads, pulsing transport flows, and cities with different metabolisms. Thanks to great new datasets and visualisation software the analogy of cities with pulsing flows is being increasingly utilised for explanatory mapping. For example the work of UCL CASA’s Jon Reades above depicts the London Underground network …

The Twitter Languages of London

Last year Eric Fischer produced a great map (see below) visualising the language communities of Twitter. The map, perhaps unsurprisingly, closely matches the geographic extents of the world’s major linguistic groups. On seeing these broad patterns I wondered how well they applied to the international communities living in London. The graphic above shows the spatial …

Mapped: British, Spanish and Dutch Shipping 1750-1800

I recently stumbled upon a fascinating dataset which contains digitised information from the log books of ships (mostly from Britain, France, Spain and The Netherlands) sailing between 1750 and 1850. The creation of this dataset was completed as part of the Climatological Database for the World’s Oceans 1750-1850 (CLIWOC) project. The routes are plotted from the …

Fast Thinking and Slow Thinking Visualisation

Last week I attended the Association of American Geographers Annual Conference and heard a talk by Robert Groves, Director of the US Census Bureau. Aside the impressiveness of the bureau’s work I was struck by how Groves conceived of visualisations as requiring either fast thinking or slow thinking. Fast thinking data visualisations offer a clear message without the need …

ESRC Benchmarking For Quant. Geography and Cartography

Profs Mike Batty and Paul Longley have been asked to write a short report on Quantitative Geography, GIS and Cartography for the ESRC’s current ‘benchmarking review’ of UK human geography, undertaken in partnership with the RGS-IBG. They would very much welcome views and contributions from QMRG and GISRG members in seeking to answer the following […]

Deceptive in their Beauty?

  Finding ways to effectively map population data is a big issue in spatial data visualization.  The standard practice uses choropleth maps that simply colour administrative units based on the combined characteristics of the people that live there (see below). These maps are popular with cartographers for a couple of reasons. You get a clear sense that the …
