What is a "leveling rod"?

A leveling rod is a long, vertical measuring tool used in surveying to determine the height difference between points. It is typically marked with measurements along its length and is used in conjunction with a level or a total station. The leveling rod is placed at different points in a survey area, and the measurement on the rod is read from a telescope or optical instrument to determine elevation differences. This tool is commonly used in construction, road building, and land surveying to ensure accurate measurements and proper grading of surfaces.
