This triangulation 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. Located near Waipahu on the island of Oahu, Hawaii, this trig point serves as a horizontal control reference with coordinates 21.50414°N, 158.05342°W. As a triangulation station, it was historically occupied during surveys to extend positional control across the Hawaiian Islands and to maintain the accuracy of local and regional surveys. Such monuments provide fixed points essential for cadastral surveys, engineering projects, and geographic data integration. Verification and documentation of benchmark locations remain valuable for surveyors conducting work requiring high positional accuracy. The point's continued recognition in professional registries supports the integrity of Hawaii's surveying infrastructure.
