PIA — NGS DL6317

This triangulation station is part of the National Geodetic Survey's network, which establishes and maintains the geometric foundation for all surveying and mapping activities in the United States. Trig stations serve as primary control points for horizontal and vertical positioning in both public and private surveying projects. Located at 21.45124°N, 158.19832°W with an ellipsoidal elevation of 18.7 meters, this benchmark is situated in the Hawaiian island region. Such points are essential for ensuring consistency and accuracy across surveying efforts, from infrastructure development to scientific research. Verification and documentation of geodetic monuments remain critical to preserving the integrity of the national spatial reference system and enabling reliable land records and engineering projects.
