The minimum diameter for the metallic cap on a surveyor's monument is 2 inches. This specification is important because larger caps provide better durability and visibility, which are essential for ensuring the monument remains intact and easily identifiable over time. A 2-inch diameter cap helps protect the underlying survey point from damage by weather, environmental factors, or human interference, making it a standard in surveying practices to ensure the monument serves its purpose effectively. The choice of a 2-inch diameter balances the need for protection and practicality in field applications, allowing surveyors to mark boundaries and other significant points reliably.
