Maps of Emotions


Visualizing human emotions on a map and investigating the human relationship with space is a relatively new component in cartography. Simple static thematic maps dealing with this topic have been around for a while. A known example is the “Map of World Happiness” by White (2007). I am not very happy with the cartographic layout however. The colour grey should be included in the legend (representing “no data” I suppose). The color black in the Caspian Sea and other big lakes is irritating.

Web scraping and mobile technology have brought new opportunities to dynamically map emotions. The World Emotion Global Trend website by Maurice Benayoun analyzes various live online sources and maps 64 emotions in more than 3000 places around the world.

A similar approach is the global Twitter Hearbeat – Tweetbeat – analyzing twitter messages for emotions and creating a heatmap from the data. See below the heatmap during the event of hurricane Sandy:

People living near nuclear power plants in Germany


I actually wanted to post this a week ago but due to lazy Easter holidays it comes a bit delayed. The topic however is still in everybody’s minds. Gregor Aisch has produced an interesting visualisation for the ZEIT magazine. It shows that in a densily populated country like Germany many people would be affected by a nuclear disaster like in Fukushima. Japan is densily populated too, however there the people seem to be more concentrated in large cities than in Germany. I heard about 80.000 people were living in the evacuation zone near Fukushima. In Germany an evacuation radius of 20km would affect 856.000 people for the plant in Neckarwestheim alone and 1.7 million around Philipsburg in case of a 30km radius. 5% of the country’s total population live within 20km of a nuclear power plant, 12% within 30km and 51% within 80km.

The south west of Germany is an earthquake risk area. However no strong quakes like in Japan have been recorded there. The strongest was 6.5 on Richter scale in Basel (CH) in 1356.

The invisible threat


The latest catastrophic news from Japan leave the impression that the disaster in Fukushima is more and more developing into Chernobyl-Dimensions. The course of events however is different in Fukushima compared to Chernobyl. Since the impact of the 1986 nuclear meltdown seem to be more and more forgotten but come back to peoples minds these days I browsed the web for some maps that show the distribution of the radioactive fallout after Chernobyl.

I also found this interesting “children-friendly” interpretation of the disaster in Fukushima:

Visualizing the Gulf Oil Spill


The Gulf Oil Spill in the Gulf of Mexico is far away for many people but what if you could move it to your neighbourhood to better understand its dimensions? Following example does just that.
