A population-centric map projection

Posted on April 17, 2010 by

Here is some material from a presentation at this year’s AAG Annual Conference in Washington DC. The presentation People powered maps: A population-centric map projection was given in the session on Topics in GIS, Remote Sensing, and Spatial Analysis and showed some new works on our grid-based cartograms (as presented at GISRUK 2009 and ESRI UC 2009).
The following animation shows the transformation of a topographic map of the United States, ending in a grid-based population cartogram (and then reversing). Please notice that loading the animation takes a while on slower internet connections:

Global Debt in 2010

Posted on April 6, 2010 by

Following the map of Europe’s external debt, here comes the same data put into global context. This map is a modified version of a work that has been made for the Times newspaper (featured in the printed edition on March, 25) in their coverage of the 2010 budget. As this picture shows, it is not only the Eurozone, but most Western countries in a deep crisis – global inequalities the other way around this time – this is a topic that will be with us for months (and years) to come and still a long way to go on the road to recovery. So, keep this picture in mind:

European debt levels in 2010

Posted on March 24, 2010 by

Alistair Darling is just about to announce the UK’s budget this Wednesday in the run-up to the forthcoming General Election, while the Eurozone countries stew over the fate of Greece and its implications for the European currency. In the reality of a world economic crisis, it’s everyone for himself, and Europe seems far from being a united community.
The following map compares the total debt of the EU-27 countries and the debt’s share of the GDP – revealing some interesting views: In sheer numbers, the PIGS are not alone (Greece, in fact, almost not counting). Eventually, we’re all in the same boat in the sea of gloom (click map for larger view)…

Vancouver revisited: Paralympics vs Olympics

Posted on March 22, 2010 by

The glowing hearts in Vancouver eventually died down with the ending of the Winter Paralympics yesterday. Time for another review and another map: The following map shows the final results of the Paralympics with the countries of the world re-sized according to the total number of medals awarded at the Paralympics (click map for larger view):

This map becomes quite interesting when opposed to the results of the Olympics. The more affluent countries dominate the whole picture again at the Paralympics, but there are some obvious differences. China disappeared, Eastern Europe grew and Canada finally managed to catch up with the United States. Here is the map of the Olympics again:

Vancouver 2010 medal count

Posted on March 1, 2010 by

The Winter Olympics in Vancouver yielded some great visualizations, with the New York Times work being amongst the top ones. They are showing off a map of the Winter Olympic Medals in the tradition of the Dorling cartograms. They also did a great job on a 3D map of the venues.
For those who want for worldmapper style maps, here is the relief: The worldmapper map of the actual medal count. The following is transformed due to a country’s total number of medals it has won.

A larger version of the map can be viewed by clicking on the image.
