1. We can see on this picture a paid parking lot, a hotel, a number of cafes and shops, an entrance to metro station, a part of a road, a bridge, some cars, lights and advertisements, wires, snow, trees, fence, flags. 2.1. This kind of bridge is drawbridge (it passes ships in the summertime). So invisible information is time in which it is opened or closed. 2.2 This parking space is not free. It means that this area is overload with cars and vehicles, so the government try to reduce it setting some price for parking. So the Invisible information might be the number of cars in each time of day/week. 3. I'll pick the first one about bridge. Information of whether this bridge and all the other bridges are up or down in each moment of time can be combined in a larger amount of information that seriously influences the traffic situation during summertime. On this basis we can create knowledge on how to design schedules for bridges more efficient in order to provide suitable traffic for both ships and citizens.
