Mobile travel guide provider Triposo has a natural interest in location-based data, as its free travel guides are automatically generated from a large collection of open datasets. To show off their expertise, they have recently created "A Year Long Snapshots around the World" [triposo.com], a short movie that reveals the exact locations in the world where pictures were taken, and that for each day of the year.
In short, the movie shows a world map in which pixels light up according to the relative amount of pictures taken. As the resulting animation is too dense and fast to make sense of, they have provided a series of snapshots to highlight some remarkable trends and outliers. In particular, they are requesting advice for some hugely popular event on 30 November that is reflected by an immense amount of photos taken everywhere in the world (although they suspect a default camera setting to be the real reason).
Watch the movie below.
