A narrative is in order. As a land surveyor of several decades, you need to add some angle data. It’s great target with the uniform incremental segments.
Are you thinking about measuring the angle of the height of the induvidual segments, as a way of calculating the percieved height or had you something else in mind?
Mathias Kp The other day I had made a reasonably long vertical angle measurement by theodolite. Distance 17,828.7 m, and a change in elevation of 342 m. If I disregard refraction and calculate the radius of the earth, I get 7,776,593 m, which is pretty similar to your radius calculation. I thought you might find that interesting.
Time stamp 0:11 on the right where you can see more of the building it is listed as 'extreme variable refraction' how have you decided that this is not the most accurate picture?
Good question. The two photos on the right were taken only 5min apart and within those 5min the view changed a lot. See this video for further details ua-cam.com/video/SmWyi7rM-NM/v-deo.html
Wow! Your average calculated radius is 7,433 km. Standard refraction is 7/6, and 7,433 x 6/7 = 6371 km, the official radius. Some would say Too good to be real. Did I miss something?
Yes a little too good, I would guess more of a coincidence, but interesting. On other days and from higher up one would get less refraction as I did in this other video ua-cam.com/video/FPo77ukuHF8/v-deo.htmlm15s
Ah, the good old Turning Torso:) Very nice, as always:)
Cheers,

Your photos are awesome of the Turning Torso. Shared
you should add sound and explanation , but nice again
True, maybe I do that in a later video.
