INU — NGS DL6319

This trigonometric station is part of the National Geodetic Survey's network of control points that establish the geometric and gravitational framework for surveying and mapping across the United States. Trig stations serve as precise positional references for cadastral surveys, engineering projects, and cartographic work. Located at coordinates 21.44933°N, 158.19685°W at an ellipsoidal elevation of 17.3 meters, this point lies within U.S. territory in the Pacific region. As a foundational control point, it provides surveyors and engineers with dependable coordinates for local and regional projects. Documentation and periodic verification of such benchmarks remain essential for maintaining the integrity of the nation's surveying infrastructure and ensuring consistency across professional geodetic operations.
