This triangulation station is part of the NGS network, which establishes the fundamental geodetic framework for the United States. Trigonometric stations of this type serve as control points for surveying, mapping, and engineering projects requiring precise horizontal positioning. Located near San Diego, California, at coordinates 32.81750° N, 117.05639° W, this benchmark contributes to regional survey networks throughout southern California. Trig stations are typically monumented points established on elevated terrain to facilitate inter-visibility with other control points. Documentation and verification of such benchmarks remain essential for maintaining the integrity of the national spatial reference system. Surveyors and engineers rely on these established positions for boundary determination, construction layout, and geographic information system development. Periodic inspections ensure the continued utility of these foundational geodetic references.
