intervisible

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

Those on the eastern side are closely clustered and would have been intervisible when they were built.

The two sites are only 30 kilometres apart and are intervisible.

In computational geometry and robot motion planning, a visibility graph is a graph of intervisible locations, typically for a set of points and obstacles in the Euclidean plane.

Between the two towns are two prominent and intervisible high points: Cottington's Hill, from which Silchester can be seen, and Quarley Hill, from which Old Sarum can be seen.
