In the equation t = α - γ + δ, which symbol represents the geodetic azimuth?

In the equation t = α - γ + δ, which symbol represents the geodetic azimuth?

• A. t
• B. Delta
• C. Gamma
• D. Alpha

Answer: (D)

Geodetic azimuth is the angle from geodetic north to a line, measured clockwise, and in surveying notation this is typically denoted by alpha (α). In the equation t = α - γ + δ, α is the geodetic azimuth—the component that comes from the geodetic reference direction. The other symbols represent different reference angles or corrections: γ usually stands for the astronomical azimuth, δ for a grid or meridian correction, and t is the resulting true or adjusted azimuth. So the symbol that represents the geodetic azimuth is alpha.
