There are a couple of visible elements: - street lamps hanging over the street - a mobile antenna on the roof of the building on the left - a tramway (cable car) These are the invisible information that can be extracted from the last two elements: 1. the quantity of mobile communications exchanged through this antenna over the time 2. the time difference of the tramway at each stop between expected and actual time; the number of passengers entering and exiting, their ticket type These information can become knowledge in this way: 1. where to put new antennas, where better/bigger antennas are needed, when to increase bandwidth during week or weekend or the day 2. in which part of the its route the tramway is mostly late, where most of the passengers stop, which tickets are most used and which the least.
