Have you ever seen the rain?

The 20th session of the Conference of the Parties and the 10th session of the Conference of the Parties serving as the Meeting of the Parties to the Kyoto Protocol is held from 1 to 12 December. For COP 20 / CPM 10 delegates from around the world increased their carbon footprint by heading to Lima, Peru, to hopefully produce more than just hot air. So again it is time to speak about the weather…or climate.

London Taxi Rides

Posted on by

Too much money, too little time? London’s taxi company Addison Lee is certainly aiming at a certain sub-section of the usual taxi customers, describing itself as a ‘business class car service’. It runs over 4,800 cars in central London and does around 25,000 journeys a day in and around the capital. For an infographic in their in-car magazine Add Lib I created a series of maps analysing and visualising the pick-up and drop-off locations of a typical week of journeys from their full fleet. This is how the drop-off locations were featured in their magazine:

World University Rankings 2014/15

Posted on by

This year’s World Science Day for Peace and Development, established by UNESCO in 2001, is promoting Quality Science Education: ensuring a sustainable future for all. According to UNESCO, the day “offers an opportunity to mobilize various partners to highlight the important role of science in society and to engage the wider public in debates on emerging scientific issues and the relevance of science in their daily lives”. While the importance of science is less disputed, the reality of ensuring scientific progress through excellent academic education remains a highly unequal matter, as many global academic rankings show.
This feature is an update to the work originally compiled last year in collaboration with Phil Baty of Times Higher Education and which first appeared in the World University Rankings. In this update I put the latest rankings results for 2014/15 into a human and economic perspective. The first two maps show the top 200 Universities from the Ranking displayed on two different kinds of gridded cartograms:

Demographies of China

Featured

Posted on by

This week I joined the Department of Asian Studies at Palacký University Olomouc (Czech Republic) as a visiting lecturer by invitation of the CHINET project. In my lecture about New Geographies of China I built on the work I have presented earlier this year at the Conference on the Socio-Economic Transition of China at the same place, teaching the students not only how China’s position is in the global context of demographic, social and economic change, but also how we can visualise this in novel ways. The following three maps are an extract from my presentation that gave an overview of this lecture.
The maps show the distribution of the different age groups in the country divided into children (age 0 to 14), working age (age 15 to 64) and elderly (above age 64) as they are counted in the official Chinese Census released by the National Bureau of Statistics. As the most recent Census figures have not been released at the same level of detail, the following three maps show the state of 2000. Here is an animated version of the three maps showing all three groups one after another (the individual maps are displayed below):

Germany’s Population Growth and Decline

Posted on by

Some time ago I have published an analysis of the changing demographies of Germany on this website (see also the map at the end of this post). I used the data from this analysis to develop some further cartogram visualisations that put the increase and decline into the focus, showing how heterogeneous these trends are evolving spatially in Germany. The following maps show gridded cartogram transformations of population change in Germany in which each grid cell (representing an equal physical space) is resized according to the total estimated population increase (right map) or decline (left map) in the period of 1990 to 2010. They show, how population patterns chances in the first two decades after reunification:

So you think you know about the United Kingdom?

Posted on by

For those not living in the United Kingdom it sometimes is a bit confusing what this strange little island next to Europe is all about. There is the United Kingdom, Great Britain, and there are England, Wales, Scotland and Northern Ireland. There is Westmister, but also Holyrood and the Welsh and Northern Irish Assembly. A lot of confusing responsibilities for such a small island.
The following series of maps shows the United Kingdom and its different countries in a series of population cartograms and explains the different countries that it consists of. Continue reading →
