Which option is NOT one of the three components of the Geodetic Control Survey?

• A. Triangulation
• B. Field Operations
• C. Geodetic Control Work Plan
• D. NAMRIA

Answer: (D)

Understanding what makes up a Geodetic Control Survey means looking at the actual steps and planning that go into establishing a precise network of reference points. The three components are the framework that ties everything together: triangulation, which builds the network geometry by measuring angles and distances to create a network of control points; field operations, the hands-on data collection in the field where measurements and observations are taken with high precision; and the geodetic control work plan, the documented plan detailing methods, station design, network layout, and schedules to ensure consistency and accuracy across the project. NAMRIA, while central to national geodetic and mapping activities, is an agency and not a step or element of the survey process itself. It serves as the institution that may oversee standards or provide data, but it is not one of the components of the Geodetic Control Survey.
