This triangulation station is part of the National Geodetic Survey's network, which establishes and maintains the foundational control points for surveying and mapping throughout the United States. Located near Hilo on the Island of Hawaii, this trig point provides precise horizontal and vertical reference data for regional surveys and engineering projects. The ellipsoidal elevation of 21.7 meters is recorded relative to current datums and reference frames. Triangulation stations of this type serve as monuments for position verification, allowing surveyors and engineers to tie local measurements into the national coordinate system. Regular documentation and recovery of such benchmarks ensure the integrity of geodetic infrastructure across the Hawaiian Islands and support applications ranging from property boundary surveys to infrastructure development. Verification of existing control points remains essential for maintaining survey accuracy and consistency in professional practice.
