GROVE — NGS TU1514 — Honolulu County, US

This triangulation station is part of the National Geodetic Survey's horizontal control network, which establishes the fundamental reference framework for surveying and mapping across the United States. Located in Honolulu County, Hawaii, this trig point serves as a monumented control station used for precise positioning and angular observations in geodetic work. Triangulation stations of this classification form the backbone of traditional surveying networks, enabling surveyors and engineers to reference their local measurements to the national coordinate system. The station's coordinates, 21.59321° north latitude and 158.04889° west longitude, position it within the Hawaiian Islands region. Documentation and periodic verification of such control points remain valuable for maintaining survey accuracy and supporting cadastral work, infrastructure development, and spatial research throughout the jurisdiction. Current condition assessments and coordinate recovery efforts help ensure the continued utility of these geodetic references for surveying professionals.
