What is the top cross section dimension used for second-order accuracy monument survey control management?

The top cross section dimension for second-order accuracy monument survey control management is 30x30 cm. This size gives a stable, square reference surface that can properly cradle the survey cap or marker plate and accommodate any witness marks, making precise re-occupation and alignment feasible. Smaller dimensions like 20x20 or 25x25 cm can be insufficient for secure cap attachment and accurate reoccupation, while a 35x35 cm surface adds unnecessary bulk without added benefit for routine second-order work. In short, 30x30 cm balances stability, practicality, and compatibility with standard equipment and cap designs.
