In 2013 German public broadcaster ARD made a documentary film about my work for their science programme W wie Wissen. This also features a range of cartogram visualisations that I produced for them. The following clip shows a compilation of the map animations that were shown in the feature, giving an impression of some of the cartographic works and visualisations that I have been working on over the past couple of years: Continue reading
Innovative maps that illustrate the most recent socio-demographic urban changes in the major city urban agglomerations in Germany have very recently been produced in a joint project of the School of Geography and the Environment at the University of Oxford and the Research Institute for Regional and Urban Development Dortmund (Germany).
The Research Institute for Regional and Urban Development (Institut für Landes und Stadtentwicklungsforschung, ILS) investigates new social processes, especially those involving urbanisation in Germany and Europe. This includes economic, social and structural processes that are compared and monitored over time to gain a better understanding of the underlying developments. Testing state-of-the-art visualisation techniques are a significant part of this effort. This was the focus of a collaboration between researchers of the University of Oxford and the ILS Dortmund which resulted in the development of a series of highly effective maps called “cartograms” that provide new insights in the changing geographies of city regions in Germany.
“Eye care for all” is the motto of this year’s World Sight Day. But there are stark global inequalities in access to eye care. In 1971, Hart described the, ‘Inverse Care Law’ as the availability of good medical care varying inversely with the need for it in the population served. Hart was describing the situation in the National Health Service in Great Britain at the time in which he practiced as both a General Practitioner and an epidemiologist.
Two recently published articles demonstrate the ‘Inverse Care Law’ on a global level. The prevalence of blindness worldwide in 2010 was reported by the WHO and verified that low- and middle-income countries, as expected, have the highest prevalence of blindness and visual impairment. In stark contrast to this, a more recent report describes the,“Number of ophthalmologists in training and practice worldwide” providing global data for the number of ophthalmologists per county and demonstrates that despite a growing number in practice the gap between need and supply is widening.
The situation is also magnified within individual countries of high, middle and low-income. For example, in France, an inverse correlation was found between the number of ophthalmologists and the prevalence of low vision for subjects of similar age and socio-professional category and another example is in Kenya where of the 86 practicing ophthalmologists, 43 are based in Nairobi (personal correspondence). That equates to 50% of the countries ophthalmologists serving 8% of an already underserved population.
We have developed two cartograms to depict the data from these two papers using Gastner & Newman diffusion-based method. This allowed us to create density-equalised maps based on the absolute values provided in the papers. In the maps, each of the reference areas (WHO regions and countries) is resized according to these values. Larger areas represent higher numbers and smaller areas proportionally smaller data values:
This is a German-language poster contribution looking at processes of change in the major urban agglomerations in Germany and novel ways of visualising these using cartogram visualisation techniques. Continue reading
Following the full cartographic roundup of this year’s general election earlier this week, here comes a related piece of research. In an article for the “In Focus” section of Political Insight (September 2015, Volume 6, Issue 2) Danny Dorling and I plotted the geography of an unexpected Conservative General Election victory.
What happened of most importance in 2015 was the rapid acceleration of a trend that has been underway in UK voting since 1979 and can be seen as having its origins in the 1960s: the increasingly uneven spread of Tory voters. The graph shows the minimal proportion of Conservative voters who would have to move seat within Britain if the Conservatives were to have an even distribution of the vote in that part of the UK at each and every General Election held between 1915 and 2015. In 2015 that proportion peaked at 19.9 per cent. When the UK becomes more polarised social pressures rise, people begin to separate more and more in their views, incomes and locations.
The 2015 UK general election is history and it seems as all stories have been told about the unexpected victory of the Conservative party. But the picture of the election is far more diverse than it seems and the political landscapes are more polarised than a conventional map of the first votes can show.
This poster, submitted as an entry to the joint BCS-SoC ‘Mapping Together’ Conference starting tomorrow in York, presents the electoral doctrine of the 2015 election. It is a cartographic roundup of the beliefs of the electorate in thirty-nine images that tell the full story of a shift in political paradigms that will shape the debates for the elections to come:
