Survey Control Marks are also referred to as what?

Explanation:
Benchmarks are fixed reference points with known elevations that serve as the anchor for all vertical measurements in a survey. When survey control marks are established, they provide a precise, repeatable datum you can compare other elevations to, ensuring consistency across maps and leveling work. Elevation marks describe a height feature but aren’t the standard term for this reference point; azimuths are directions, and slope is a gradient. So the best term for survey control marks is benchmarks.
