Morphology
The meaning is directly compositional: 'azimuth' (an angle/direction from north) modifies 'mark' (a sign or point), so together they denote a mark indicating a specific azimuth or direction. This follows a regular noun+noun technical compound pattern and would be inferable by a learner who knows both constituent words.
Etymology
Azimuth mark is a visible mark placed on the ground or a rock to show the exact azimuth — the direction from true North — from a fixed point. That's why it means 'a marked point used to indicate an exact azimuth direction' and helps surveyors align their instruments.
