This triangulation station is part of the NGS network, which establishes the fundamental control framework for surveying and mapping throughout the United States. Located near Philadelphia, Pennsylvania at coordinates 39.89306°, -75.16694°, this trig point serves as a reference monument for horizontal geodetic control. Triangulation stations of this type have historically provided precise positional reference points for surveyors conducting boundary surveys, engineering projects, and cartographic work across the nation. The point's coordinates enable surveyors to establish local control networks with known accuracy relative to the national datum. Verification and documentation of such benchmarks remain valuable for professional surveying practice. Regular inspection and confirmation of monument condition and position integrity support the continued utility of the NGS control network. Professional surveyors rely on these established reference points to maintain consistency and accuracy in their work across generations of projects.
