1. Visible information: The picture shows part of the historical center of the city and the surrounding green hills/mountains, it highlights the density of the buildings, the homogeneity of the colours of the materials and the height of the buildings with some emerging monuments. The position of the city in the plain (near the "invisible" river) in relation to the surrounding hills. 2. Invisible information: the touristic interest of the city, the choice of the city government to conserve the image of the city, the difficulties of circulation (cars, public+private transport, air pollution, noise) 3. How this information can become knowledge: analysing circulation difficulties of public+private transport - monitoring air pollution and noise due to circulation.
