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:

Mapping the 2012 Olympic Medals


Esri’s map portal “story telling with maps” has come up with a visualization of the distribution of the London Olympic medals by country. They also offer ways to create your own story telling web map. I also recommend the article on “Telling Stories with Maps” on Esri Insider.

Some interesting data sources in relation with the 2012 Olympics:

Guardian: London Olympics 2012: where does the money come from – and where’s it being spent?

Data from Transport of London: https://api-portal.tfl.gov.uk/

Dude, Where’s My Phone?


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.

A Dutch project called Nederland van Boven (Netherlands from above) shows beautiful interactive maps and visualizations.

The making of video on YouTube is particularly beautiful:

Visualizing spatial information with light painting


Following video can be found among the “Best Data Visualization Projects of 2011” on FlowingData. Light painting is used to visualize invisible wi-fi signal strength – a way of thematic mapping in the broader sense.

Web Cartography without Flash


Recently I found some interesting examples on how to build an interactive map without Flash but using HTML5 and JavaScript instead. This seems to open new possibilities to visualize free and open data. Avoiding Flash would also be more congruent with the open source idea.

1) migrationsmap.net   –   via webappers.com

The migrationsmap code is available on github!

2) American Migration Map for Forbes   –   the editor Jon Bruner describes on his blog how he created the map.

More things you can do with Open Data


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:
