The loss of your smartphone can be painful nowadays. The people at Lookout who offer mobile security services have come up with some interesting interactive maps, visualizing how often and where people loose there mobile phone.
The value of phones getting lost every year is impressing but some other surprising things can be discovered: For instance in Moscow the second most likely place to loose your smartphone is the military base. Where in Seoul people tend to loose it at the Martial Arts Dojo and in Brussels it is the dentist who sits on a large amount of left behind smartphones.
Not always is it meaningful to map everything that has a coordinate. Recently visualisations of road fatalities appeared on the web that used public data to show every death on every road in a relatively large period on a map. The amount of data concerned resulted in a map that looks similar to a visualisation of the traffic density, which highly correlates with the population density. Hence, this map does not really provide a new perception. I’ll give following map by the BBC as an example:
A smart but simple visualisation by FlowingData breaks the data down into seasonal variations instead of spatial ones. This way new interesting trends become visible like the higher number of accidents on weekends or through the summer months.
In case one wants to use the coordinates included in the data, it would make sense to combine it with other spatial information such as traffic density on certain road sections. This way spatial centers of gravity for road accidents could become visible.
I recently came across the blog by Marian Steinbach. There are some interesting visualizations using open data from long time air pollution measurement in Nordrhein-Westfalen (Germany) as well as radiation data from Germany and Japan. Hava a look:
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.
