@Kemas-Dimas thank you for the description regarding the first link. very helpful. unfortunately, the further link contained therein for the alignment of the angle for the panoramas does not work. 
does this function no longer work? So is the start angle of the panoramas left to google?
What is currently the most likely way to get a certain starting angle to the panoramas?
I would be very happy if I would get help with this.
best thanks and greetings
Martin
