Notes:
- on the way out and back, there was a car parked between 'outdoor' and 'underpass_entry'. So I had to go around it.
- 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.
