This triangulation station is part of the National Geodetic Survey's network, which establishes the foundational control points for precise surveying and mapping across the United States. Triangulation (trig) stations serve as reference monuments for horizontal positioning, enabling surveyors and engineers to conduct accurate measurements and coordinate spatial data. Located near Clyde Hill, Washington, this point contributes to the geodetic framework for western Washington State. The coordinates 47.63026°N, 122.21332°W place the station in the Puget Sound region. Verification and documentation of such control points remain essential for maintaining survey integrity over time. As reference monuments may be disturbed, destroyed, or their accessibility altered, current condition reports and coordinate confirmation support reliable land surveys, infrastructure development, and geodetic studies across the region.

Is this point verified and usable for professional surveying?

This record has been community-verified 0 times. Data quality depends on the source: NGS and official national agency points are typically centimetre-accurate, OpenStreetMap survey points are metre-accurate, and GeoNames topographic landmarks (peaks, hills) are reference-grade only. Always cross-reference with the original agency datasheet before using this point for cadastral, legal, or safety-critical work.

Original source: this record was imported from ngs_public. Always refer to the original datasheet for the most up-to-date and authoritative data.
