Sightlines

Sightlines

A sightline, sight line or visual axis, is a normally unobstructed line-of-sight between an intended observer (or spectator) and a stage, arena, or monument, for example. Sightlines are a particularly important consideration in theatre and stadium design, road junction layout and urban planning. In cities such as London, construction within sightlines is restricted to protect the key views of famous landmarks.

Objects that have a direct line of sight with one another are said to be intervisible.
