Eric Fischer on Flickr has published a photoset that examines the GeoTagging information in each Flickr photograph of a city and analyses the users behaviour to establish whether the photographer can be classified as a “local’ or a “tourist”. For example a tourist takes pictures of lots of different locations in a month, a local takes lots of pictures in the same area over a longer period of time. He then produces a map of the city showing who took pictures where (blue = local, red = tourist, yellow = uncertain).
The Buenos Aires one is interesting in that there is very little blue in there, it’s mostly big blotches of red. The “V” on its side in the middle is Congreso bottom left, Avenida de Mayo leading to Plaza de Mayo and the Diagonal skewing up and to the left towards El Obelisco. Towards the bottom the concentrations are El Caminito and La Bombonera in La Boca and the large blob in the centre towards the top is Recoleta Cemetery. Other hotspots include El Puente de la Mujer in Puerto Madryn and Plaza San Martin (north of Plaza de Mayo)
