Fabien Girardin is a Ph.D. student in Computer Science and Digital Communication at the Interactive Technology Group at the Pompeu Fabra University in Barcelona, Spain. His current investigation explores the people perception of discrepencies in the context of collaboration supported by mobile and ubiquitous environments.In continuation of Fabien's exploration of Flickr geotagged images, he produced the "traces" left in Flickr by tourists and citizens of Barcelona based on around 4000 images taken between October and December 2006.
A trace consists in an ordered set of geotagged images taken by one person in one day. The data and visualizations remain brut, but there might be a potential to define and confirm patterns of how tourists navigate the urban space (e.g. the elephant path along the Rambla, people do not walk to Gaudi's Sagrada Familia). The maps do not carry the sense of time yet to highlight when and where the traces start and end.
