SOH 46 — NGS DR2108 — Waipahu, US

This triangulation station is part of the National Geodetic Survey's network, which forms the foundation of the United States' official geodetic control infrastructure. Trigonometric stations serve as primary reference points for large-scale surveying projects, mapping, and engineering works requiring precise positional data. Located in the Waipahu area of Hawaii at coordinates 21.42628°N, 158.05428°W, this point contributes to regional geodetic coverage across the Hawaiian Islands. Such control stations enable surveyors, engineers, and cartographers to establish local surveys with known accuracy relative to the national datum. Verification and documentation of benchmark locations, coordinates, and physical condition remain essential for maintaining the integrity of the surveying network. Professionals relying on this control point should consult current NGS records for any updates regarding monument stability, accessibility, or coordinate refinements resulting from periodic resurveys.
