Blogger Christian Pearson compiled data from the National UFO reporting center, and created a map which shows all registered UFO sightings between 1933 and 2015. The visualization has been created in cartoDB.
The story begins in 1933 with the first UFO sightings being spotted over California and Nebraska in the US, the UK and France in Europe, and locations in Japan and Australia. When you watch the map closely, you’ll notice that the number of sightings really increases around the 1950s and 1960s. It’s a Cold War times. Where countries tested a lot of weapons and aircrafts.
Cartographically speaking the map is not the most brilliant data visualisation ever but it definitely shows that cartDB gives some cool possibilities.
