Lego maps

John Nelson‘s blog post on Lego-ified maps inspired me to play around with some satellite imagery myself. John’s description of the process is very clear and easy to follow. The only thing I’d add is a recommendation to use a graphics software that has a...

Updated global GeoHipster map

I’ve updated the GeoHipster Map, i.e. the map of the followers of @GeoHipster that I initially published in 2014. Of course, this map is not to be confused with the authoritative Map of GeoHipster Sightings over at the headquarter. Mine is like the theoretical spatial...

Switzerland tile map

(Blogpost auf Deutsch unter www.geo.ebp.ch) I believe in abstraction for conveying information, or ‘rough’ context for information, efficiently. Since a while, hex and square tile maps are all the rage in the US. Check out this post by the npr visuals team on the technique,...

To all you Geohipsters out there

Have you heard of the Geohipster blog? It’s the self-described place for people who ‘grow their own organic vertices, use gluten-free topology or only geocode by hand, in small batches’. And I give at a big recommendation, put it into your feed reader. And relax, you don’t need to be a...

Some, just a little, history: Over the last few years, I have been collecting Switzerland-based Twitter users that talk about topics...

What Google Autocomplete tells us about countries

Together with my collaborators in the “Information Geographies” project at the Oxford Internet Institute, I have published a blogpost that analyses Google Autocomplete. This is seemingly a popular pastime these days, but unlike the maps I have seen so far, we don’t just map the most...

The online perspective: Africa on Wikipedia

My friends and colleagues at the Oxford Internet Institute, Mark Graham and Stefano de Sabbata, are compiling a collection of maps and visualizations at geography.oii.ox.ac.uk that give insight into the contemporary geographies of knowledge: Which places are connected with the online world? Which places are participants in the...

Hexagons, quasi-maps and cartograms

Some months ago I mapped Switzerland’s administrative regions using a hexagonal cartogram. That idea was inspired by pioneering work of the Leicestershire County Council. After consulting with experts in the field – Leicestershire’s Alex Lea, Danny Dorling of Worldmapper (currently at the University of Oxford) and Adrian...
