If there is an accessible observation deck, I would see them as look-out towers, not sure if "observation tower" is the right term for these, might be confused with things like wildlife observation towers, but I may be misguided. > > 2.

Phones nowadays provide more or less precise apps for the estimation of heights (e.g. with AR), but for almost any significant tower you will also find precise documentation about their height.
