What is visible? The picture shows the Sheffield railway station to the left, the Sheffield College campus to the right and some university buildings in the bottom half. In the distance there is a park and it can also be noticed that the residential areas around the park have a higher tree density than the non-residential spaces. One of the key-things to notice in this image is the fact that Sheffield is not a city that has been built or is being built vertically, but rather horizontally, with many buildings with only 2 or 3 stories high but spread across the available land. Some parking lots are also easily spotted. What is invisible? A lot of the buildings are not used, as they have been built during the industrial period and they do not meet the building requirements nowadays. There are less and less trees around the city as they are being removed in order to have new buildings raised. Relating this to the previous point, this becomes an upsettingly inefficient way of urban development, as old buildings are neither demolished nor refurbished to be used, but the green spaces are taken away by newly built structures. Even though we see the railway station, one of the main roads and a few parking lots, information regarding how many people travel by train, car or just walk is not available, as it is strictly related to particular points in time. Their whereabouts are also invisible information and I think this would be interesting to find out as a lot of buildings with a completely different use are close to each other. If this information was be available, better planning would become a reality: the city will have parking lots where they are needed and not where there was once an unused empty space, bike racks would be put around the areas where they are needed the most and a better connection of the buildings with a high-usage (such as university buildings) where the flow of people is constant to the nearby roads or means of public transportation.
