1. In the photo, we can see a festival in Szczecin (Poland). It is crowdy, lots of people are spending their free time here (as it is Saturday). Moreover, we can see that during this event people meet each other and have fun. There are people from different age groups, old ones as well as young families with their children. What is also visible, is that many ships and yachts are docked to the embankment. On the other side of the street, there is a trade area. Last but not least, we can see that people are walking along one of the main communication arteries in the city. 2. First invisible information that can be extracted out of the visible information of this photo is a traffic in the city during this event (as one of the main communication arteries in Szczecin is closed) and in consequence a demant for public transportation system. Second invisible information, is how many people from different age goups take part in this event, and elaborating the topic, how many families are with their children. Which direction do they pick and how their track through the festival looks like. 3. If we know, how many families come with their children and how does their path to, in and out look like, than we can work on safier space for this group of people and may create a system that could help to avoid child loss in such a crowd.
