What is a grid azimuth?

• A. Angle between grid north and a straight line plotted between two points
• B. Angle between magnetic north and a line of direction
• C. Angle between true north and a plotted line
• D. Angle between the compass and a line

Answer: (A)

Grid azimuth is the angle measured clockwise from grid north to a straight line drawn between two points on a map. Grid north runs along the map’s grid lines, defined by the map itself, and is different from true north (geographic north) and magnetic north (where a compass points). So the grid azimuth specifically uses grid north as the reference direction. This makes it the exact description of the angle between grid north and the line. In contrast, angles relative to true north or magnetic north describe true azimuth or magnetic azimuth, and a compass reference would relate to headings rather than the map grid.
