JRF B — NGS DR8486 — Kapolei, US

This trigonometric station is part of the National Geodetic Survey network, which establishes and maintains the fundamental geodetic control framework for the United States. Trigonometric stations serve as precise spatial reference points essential for surveying, mapping, and engineering projects requiring accurate horizontal and vertical control. Located near Kapolei on the island of Oahu, Hawaii, this benchmark occupies an important position within Hawaii's geodetic infrastructure. The ellipsoidal elevation of 18.7 meters provides vertical reference data for the region. As part of the NGS network, this point contributes to local, state, and national mapping accuracy and supports infrastructure development, coastal zone management, and scientific research. Documentation and periodic verification of such control points remain critical to maintaining the integrity of geodetic networks and ensuring reliable spatial data for professional surveying applications.
