To measure the horizontal and vertical position of a new survey control point, you need to start your survey on at least 2 known points (3 preferred for checks). For example, if you start at a control point of order AA and measure a 500 km distance, the length of the line should be accurate to within 3 mm base error, plus or minus 5 mm line length error (500,000,000 mm 0.01 parts per million).

A control point may have one or more of these values attached to it. 2. The term benchmark, bench mark, or survey benchmark originates from the chiseled horizontal marks that surveyors made in stone structures, into which an angle-iron could be placed to form a "bench" for a leveling rod, thus ensuring that a leveling rod could be accurately repositioned in the same place in the future. Setup your total station on existing survey control point Pt 101, setup targets on existing point Pt 100, and new control point Pt 200. 0000015002 00000 n A temporary benchmark in surveying is a control point that is set by a surveyor to base other points off of.
