The smaller horizontal angle between the true meridian and a survey line, is known as-
-
A.
True bearing
-
B.
Arbitrary meridian
-
C.
Azimuth
-
D.
Magnetic bearing
Correct Answer:
C. Azimuth
Explanation:
The smaller horizontal angle measured between the true meridian and a survey line is defined as the azimuth. Unlike a true bearing, which is measured from either the North or South towards the East or West (ranging from 0 to 90 degrees), an azimuth is typically measured clockwise from the north meridian. Since the true meridian is a fixed reference line passing through the geographical poles, the horizontal angle relative to it remains constant for any specific line, making azimuth a standard reference in surveying and navigation.
