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:

The Netherlands from above


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:

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.

Thematic Mapping with OpenStreetMap


OSM user SK53 shows on his blog what potential exists in the OSM-data. Together with population related Super Output Areas from the British Government an interesting map on the pub density in the UK has been developed. The data quality of OSM however is not consistent throughout the UK but nevertheless I think some interesting relations can be seen in the map. The focus map on London shows how the pubdensity is concentrated in the center and is relatively low in the suburbs.

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.

An interesting more comprehensive WebGIS platform that integrates community data can be found here:

Geotagger’s World Atlas – Tourists compared to Locals


The Geotagger´s World Atlas on flickr depicts the numbers of pictures taken at a certain location. They cluster around certain areas of interest in cities and are sometimes interpreted as maps of tourism. Locals and Tourists distinguishes between the pictures taken by locals and those taken by tourists. For some cities they reveal some interesting differences between the locals and the tourists pattern.

The data reflects in first place the amount of geotagging activity and indirectly the participation in flickr it can also give a clue to what extend a city is touristy. Las Vegas for instance shows a lot of red areas while Kansas City is mostly blue at a general lower number of geotagged images. This way as a tourists one might get hints to places that are popular by locals but not yet overrun by tourists.

Blue stands for locals, red for tourists, yellow might be by either.

Are thematic maps objective?


I recently came back from the 58th German Cartographer’s Conference in Berlin. A highlight was a speach given by the French cartographer Philippe Rekacewicz who is working for the United Nations Environment Programme and the French newspaper Monde Diplomatique that is translated in many languages. The title of his speach was “Drawing the world: cartography between science, art and manipulation”. Rekacewicz indeed has returned to drawing the world on paper with pencil for the sake of not being limited by the visualization capabilities that a digital system offers. Using this basic way of visualisation the emotion comes into his work as it is the case in a handmade piece of art. This way the work is of course subjective as Rekacewicz states – it reflects the cartographer’s view on the world or how he would like to visualize it making maps a possible tool for manipulation. However the maps he shows are based on real data making them a part of the scientific domain as well.

Many of Rekacewicz’s work can be found in the Atlas on Globalisation from Monde Diplomatique. Unfortunately it is only available in French and German. Some people critisize it for not being neutral. But being neutral was probably not the intention. As said before a map is just one point of view. We cartographers are would-be emperors we draw borders and move mountains when we desire.

Below is a map from Monde Diplomatique that I find very impressing. It shows the European measures to seal itself off from immigrants. It is probably based on one of the typical pencil sketches by Rekacewicz that I added for comparison. The sketch reflects some of the author’s anger when producing that map. The Schengen-border is drawn as a (bloody) red line including number of deaths through attempts of crossing the border. More on the topic can be found here.
