![San Valentin, A Coruña, Spain][1] 1_Visible Information: This is “San Valentin” neighborhood in Fene, A Coruña, Spain. I live in this place so I can see daily this small entrance avenue surrounded by buildings, pedestrian paths, bike paths and green fields. This neighborhood is a working-class living place quite near to a big shipyard where used to work huge amount of the population in this area. We can see also streets, cars, power lines, woods, and a well structured and classic distributed buildings. 2_Invisible Information: 2.1_water supply: You can not determine the quality and capacity of the water supply network for this area, nor the comsuption of water from the different buildings and families living there. This example of invisible information would apply for other facilities as well (lighting, electricity, telecomunications, waste disposal collection, etc). 2.2_Population: You would be able of counting the amount of houses and flats but you wouldn´t be able of accounting for the number of people living in this place. 3_Knowledge: 3.1_Water supply network and popullation: In this case, combining the two pieces of invisible information, we will be able of designing, building and mantaining a correctly-sized water supply network, predict the consumption or analyzing our supply during the droughts.
