Benchmarks are used to identify which of the following?

Benchmarks serve a crucial role in identifying latitude, longitude, and elevation. These fixed reference points are established by surveying organizations and are used to ensure consistency and accuracy in geographic positioning and elevation measurements. They are typically marked on physical monuments or plaques and include precise information about their geographic coordinates and elevation above a predefined reference point, such as sea level.

In the context of surveying and land measurement, benchmarks provide essential data for a variety of applications, including construction, civil engineering, and natural resource management. They help in determining the height of land parcels and in establishing accurate geographic data needed for mapping and land development projects. This makes them indispensable for professionals who require reliable elevation data to complete their work effectively.
