What does 'Indefinite or unsurveyed' indicate on Marine Shorelines Symbols?

• A. A clearly defined boundary.
• B. A boundary that has not been surveyed or defined.
• C. A boundary determined by vegetation.
• D. A boundary that marks the edge of water.

Answer: (B)

In marine shoreline mapping, symbols convey how certain the boundary position is. Indefinite or unsurveyed means the boundary has not been measured or fixed on the ground, so its exact location is not known. The line shown is approximate and could change with new survey data, signaling that more work is needed to pin down the precise boundary. This differs from a clearly defined boundary, which has a precise surveyed position. It’s also not describing a boundary based on vegetation, nor simply the edge of the water, which are different kinds of boundary ideas.
