What two geographic coordinates are used to specify the location of charted objects?

• A. Latitude and longitude
• B. Bearing and range
• C. Speed and heading
• D. Depth and color

Answer: (A)

Latitude and longitude are the coordinates used to specify a location on the Earth's surface. Latitude measures how far north or south you are from the equator, while longitude measures how far east or west you are from the prime meridian. Together, they form a global grid that uniquely identifies any charted object anywhere. Other options describe movement or attributes rather than fixed position: bearing and range give a direction and distance from a reference point, not a global location; speed and heading describe how a vessel is moving; depth and color describe characteristics of features rather than where they sit on the map.
