KAENA POINT RADIO MAST — NGS TU1589

This triangulation station is part of the National Geodetic Survey's fundamental control network, which establishes the geometric framework for surveying and mapping throughout the United States. Trig stations of this type serve as fixed reference points for horizontal positioning, enabling surveyors and engineers to establish local coordinates for construction, boundary determination, and geographic information systems. Located in Hawaii at coordinates 21.56207°N, 158.24803°W, this benchmark contributes to regional geodetic control in the Pacific. The elevation value has not been recorded in available documentation. Recovery and verification of such control points remains important for maintaining the integrity of the national spatial reference system and for validating modern positioning technologies. Surveying professionals should note the documented coordinate values when establishing local survey networks or performing accuracy assessments in this area.
