This triangulation station is part of the National Geodetic Survey's network, which establishes the primary geodetic framework for the United States. Trig stations of this classification serve as control points for surveying and mapping operations, providing accurate horizontal position references across regions. The coordinates place this benchmark in Hawaii, where such control points support local survey work, engineering projects, and geographic information systems applications. As with all NGS monuments, verification and documentation of this point's current condition and accessibility contributes to maintaining the integrity of the national geodetic infrastructure. Surveyors and GIS professionals rely on confirmed benchmark locations for high-precision work. The absence of recorded elevation data underscores the importance of field visits to fully characterize such stations for contemporary surveying practices and archival purposes.

Is this point verified and usable for professional surveying?

This record has been community-verified 0 times. Data quality depends on the source: NGS and official national agency points are typically centimetre-accurate, OpenStreetMap survey points are metre-accurate, and GeoNames topographic landmarks (peaks, hills) are reference-grade only. Always cross-reference with the original agency datasheet before using this point for cadastral, legal, or safety-critical work.

Original source: this record was imported from ngs_public. Always refer to the original datasheet for the most up-to-date and authoritative data.
