I'm not too fussed about exact building height, but exact metrics for roofline down to about floor 20 would be more than useful, even more so per-floor with detail from visible window top and bottom.The funny thing is I'm not sure anyone ever actually measures the exact height of a building. I've been a builder for many years and it's always just a figure derived from the plans. There are way to many variables and frankly (unless your going for a world record)* it's not that important.
* note: even record setters are constantly being re-examined.
I've used the NIST values for now, but even though they had the plans they still state the metrics as approximate.
No idea if that's nearest inch, foot, metre, ...
Very annoying such simple detail is not available.
