CROSS ON ROCK WALL 1964 — NGS TU1579

This trigonometric station is part of the National Geodetic Survey's network, which establishes the fundamental control framework for surveying and mapping activities throughout the United States. Trig stations serve as precise horizontal control points, typically established at elevated locations to facilitate sightlines for triangulation work. Located in Hawaii at coordinates 21.58093°, -158.17239°, this point contributes to regional geodetic control in the Pacific area. The elevation data for this particular station has not been recorded in available documentation. Surveyors and mapping professionals rely on verified benchmark data to ensure accuracy in subsequent surveys, engineering projects, and infrastructure development. Documentation and periodic verification of such reference points remain essential for maintaining the integrity of the nation's geodetic infrastructure and supporting accurate spatial positioning across diverse applications.
