This trigonometric station is part of the National Geodetic Survey's network of control points that form the foundation of the United States' official geodetic reference system. Located near Redmond, Washington, this trig point serves as a precise horizontal and vertical control station for surveying, mapping, and engineering projects throughout the region. The ellipsoidal elevation of -5.0 meters reflects the point's position relative to the GRS 80 reference ellipsoid. Trig stations of this type are established to enable accurate measurements across large areas and to support the densification of geodetic control networks. Verification and documentation of such benchmarks remain essential for maintaining survey accuracy, supporting infrastructure development, and ensuring consistency in geospatial data. Regular confirmation of these reference points helps preserve the integrity of the national spatial reference system for both public and private surveying operations.
