This triangulation station is part of the National Geodetic Survey's trig network, which establishes precise horizontal control across the United States and its territories. Located in Honolulu County, Hawaii, this benchmark serves as a reference point for surveying and mapping operations throughout the Hawaiian Islands region. Triangulation stations of this type are fundamental to geodetic networks, providing accurate coordinate positions that support cadastral surveys, engineering projects, and geospatial data collection. The NGS network remains essential to Hawaii's surveying infrastructure despite advances in satellite positioning technology. Verification and documentation of benchmark locations, coordinates, and physical condition help maintain the integrity of the control network and ensure that surveyors can access reliable reference points for professional work. Such monuments contribute to long-term geodetic stability and consistency across surveying disciplines.
