The history team will visualize this change over time. As far as it has been possible, members of the team have found places where an older picture was taken, then take a new one today and compare. It has often proved difficult. Where the photographer stood several ten years ago, today it is impossible to take a new picture that shows the change. You have to move, often several ten metres, to a new place, which of course sees the change, but it is often from a completely different angle. Most of this applies to vegetation that grows up. but also buildings that have come in the way.
