They've used a vision transformer to estimate building heights from monocular aerial photographs, so they're guesses at best. Calling this a map is a stretch.

I checked the building heights where I live vs the actual heights, sometimes they display the height as half of what the actual height is.

I found a few that are off by a factor of about 4. Always lower than in reality, never taller.

Hey maps used to have sea serpents and winged griffins. It's a map. Maybe not the best map.
