Speaking of which, one way we can perhaps measure the skyline is by taking an area of the city where the skyline falls under, and the size will be the sum of all the building x their building height (m.)
Though, we can even tweak this formula. Since a building over 100m would have a larger effect than a building under 100m. Such an effect should be incorporated into the formula. So, for each building that is over 50m, there will be a coefficient - I don't know, say 1.25 for each building over 50m, and 1.5 for each building over 100m, 2 for each building over 200m...
Other factors can be for historic merits. Thus, any building built before 1950 gets a factor of 1.5 + any building before 1920 gets a factor of 2.0.
A final factor for landmark, if the building has a landmark status, then, x 2.0
Skyline Size = Sum of (Building Height * Height Factor * Historic Factor *Landmark Factor)
