D 245 — NGS TU0657 — Waipahu, US

This triangulation station is part of the NGS network, which establishes the fundamental geodetic framework for the United States. Trig stations serve as fixed reference points for surveying, mapping, and construction projects requiring precise horizontal control. Located near Waipahu on the island of Oahu, Hawaii, at coordinates 21.48161°N, 158.04708°W, this benchmark contributes to Hawaii's integrated position control network. Such monuments enable surveyors to perform accurate measurements and coordinate determinations across diverse terrain. Documentation and periodic verification of these reference points remain essential for maintaining the integrity of the national geodetic datum. Professional surveyors rely on NGS trig stations to ensure consistency and accuracy in their work. The preservation and proper documentation of this station's position and characteristics supports continued utility for surveying and engineering applications throughout the region.
