He does overlay a calculation tool on the map to work that out I believe. I don't have time to watch all 3 again. Maybe someone else can chime in who has watched it but I am confident he took the north position into account correctly as that is obvious. It does work like a sun dial. His times would be way out if he had not done it correctly IMO.He didn’t not identify true north in the BG video. At approx 5:45 he states that BG is at the SE end of the bridge and the shadow angle is more north than straight across which would’ve been more 3 o’clock. At approx 7:05 he states that BGs shadow is more north than the lines on the bridge.
The bridge runs NW to SE according google earth. LG is taking the pic at a funky angle so it looks like the bridge runs NE to SW. the AW pic is more the way the bridge is oriented, but the angle LG took it is funky too.
I don’t think you can just orient the photos to point N and S and get accurate info. If he placed the bridge in its true orientation and determined north in relation to the bridge then assessed the shadow I think it would be more accurate. I do not have a program easily accessible that would allow me to manipulate the photo like his does. I do have an associate that does and I might have to hit him up. Kind of a unnecessary really because I’m confident LE knows the actual times.
I give him loads of credit for coming up with this. The theory is clever, I’m just not sure about the execution. Maybe his program somehow does all of this for him? Idk.
Edit: this is based on my understanding of how sundials work. They have to be oriented a certain way and 12 faces north
