CC 177 — NGS TU1700

This triangulation station is part of the National Geodetic Survey's network, which provides the foundational control for surveying and mapping activities across the United States. The trig point type indicates this station was established as part of classical triangulation surveys and serves as a reference for horizontal and vertical positioning work. Located at coordinates 21.46036°N, 158.21334°W in Hawaii at an ellipsoidal elevation of 87.2 meters, this benchmark contributes to the national spatial reference system. Trig stations of this type support cadastral surveys, engineering projects, and geodetic measurements throughout their regions. Verification and documentation of such control points remain essential for maintaining survey accuracy and enabling professionals to establish local survey networks with confidence in their relationship to national datums.
