This triangulation station is part of the National Geodetic Survey's network of control points that forms the foundation of the United States' surveying and mapping infrastructure. Located near Audubon, New Jersey, at coordinates 39.89488°N, 75.07189°W, this trig point serves as a geodetic reference for regional surveys and positioning work in the Mid-Atlantic region. Triangulation stations of this class have historically provided fixed points of known horizontal and vertical position, enabling surveyors to extend accurate measurements across large areas. The ellipsoidal elevation of -17.4 meters reflects the point's position relative to the reference ellipsoid rather than mean sea level. Documentation and periodic verification of such control points remain essential for maintaining geodetic accuracy across professional surveying, engineering, and mapping projects. Surveyors rely on the NGS network to establish local project baselines and validate modern GPS and measurement techniques.

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.
