This triangulation station is part of the National Geodetic Survey's network, which establishes the fundamental control framework for surveying and mapping throughout the United States. Located near Kapolei on the island of Oahu, Hawaii, at coordinates 21.32661°N, 158.01931°W, this trig point serves as a reference station for local and regional surveys. Triangulation stations of this type have historically provided precise horizontal control by serving as intervisible points in networks of measured angles and distances. Documentation and verification of such benchmarks remains essential for maintaining the integrity of spatial reference systems used in surveying, mapping, and geospatial analysis. Surveyors and GIS professionals rely on accurate positioning of control points to ensure consistency in property boundaries, infrastructure projects, and natural resource management across Hawaii and the broader geodetic network.
