Notes:
- Because of the people between '8-inner_door' and '9-inner_door_2', '17-inner_door_2' and '18-inner_door', and '18-inner_door' and '19-outerdoor_2', I had to manoeuvre around them.
- On 15th Nov. 2023, there was an event going on the ground floor of building D (between markers '7,19 - outerdoor_2' and '9,17 - inner_door_2'). Thus, the data of these regions for this day may look a little different than the other days as often I had to manoeurve around the people, the stalls or the posters.
