demarcate

Israel's military currently holds about half of the territory, demarcated by a so-called Yellow Line.

The Comoe River clearly delimits part of the northeastern frontier between Ivory Coast and Burkina Faso -- but the land border is poorly demarcated.

The Israeli military said soldiers had fired at a "suspicious vehicle" that had crossed the so-called yellow line demarcating the area still occupied by Israeli forces in Gaza.

China Customs said that the maps also did not contain the nine-dash line, which demarcates Beijing's claim over nearly the entire South China Sea.

China claims by far the largest portion of territory in an area demarcated by its so-called "nine-dash line".
