HOW WE DEFINE THAT THIS POINT IS HIGH ANT THAT POINT IS LOW BY STAFF READING?

Question

Accepted Answer

Staff readings can determine the elevation difference between points.

Staff readings involve using a leveling instrument, such as a level or a theodolite, to measure the vertical distance between two points.
A high point is determined when the staff reading at that point is greater than the staff reading at a nearby lower point.
A low point is determined when the staff reading at that point is smaller than the staff reading at a nearby higher point.
Staff readings are commonly used in surveying and construction to establish elevations and contours of the land.
For example, if the staff reading at Point A is 5.2 meters and the staff reading at Point B, which is downhill from Point A, is 4.8 meters, then Point A is considered higher than Point B.
