KEOPUKA — NGS TU2541 — Hawaiʻi County, US

This triangulation station is part of the National Geodetic Survey's network, which establishes the fundamental horizontal control framework for the United States. Located in Hawaiʻi County, Hawaii at coordinates 19.48746°N, 155.94975°W, this trig point serves as a reference station for surveying and mapping operations across the Hawaiian islands. Triangulation stations of this type provide precise positional data essential for cadastral surveys, engineering projects, and geographic information systems. The NGS network ensures consistency and accuracy in spatial reference across diverse terrain and jurisdictions. Documentation and verification of such control points remain critical for surveyors and government agencies conducting work in Hawaii, particularly in areas where updated geodetic infrastructure may be limited. Maintaining accessible records of established reference points supports continued accurate surveying practice and prevents costly errors in future projects.
