PROTESTANT CHURCH — NGS TU1521 — Honolulu County, US

This triangulation station is part of the National Geodetic Survey's network, which establishes and maintains the fundamental geodetic infrastructure for the United States. Triangulation stations serve as precise reference points for surveying, mapping, and engineering projects across their regions of coverage. Located in Honolulu County, Hawaii, this benchmark contributes to the spatial control framework for the Hawaiian Islands. Trig stations such as this are typically established at elevated or strategically visible locations to facilitate inter-visibility and measurement accuracy in surveying operations. Professional surveyors and mapping professionals rely on NGS control points to reference local surveys and maintain consistency with the national coordinate system. The documentation and verification of such benchmarks remain valuable for confirming positional data, supporting infrastructure projects, and preserving the accuracy of geodetic records. Surveyors working in this region should verify current station conditions and accessibility before use in precision work.
