On quad maps, horizontal control station marks are depicted as which symbol?

• A. Black outlined triangles with a dot in the center
• B. Red circles with a dot in the center
• C. Green squares with a dot in the center
• D. Blue diamonds with a crosshair

Answer: (A)

On quad maps, horizontal control station marks anchor the map’s geographic coordinates and are shown as a black outlined triangle with a dot in the center. The triangle shape signals that this is a triangulation or network control point, while the central dot marks the exact location. This symbol is designed to stand out from other map marks, so you can quickly identify precise horizontal control points used to calibrate positions across the map. Other colors and shapes on the map represent different features or types of control, so they don’t indicate horizontal control marks.
