This triangulation (trig) station is part of the NGS network, which establishes the fundamental geodetic framework for the United States. Located in the Philadelphia, Pennsylvania area at coordinates 39.94725°, -75.15057°, this point serves as a control station for horizontal positioning and surveying operations across its region. Trig stations of this type were historically established to create accurate networks of known positions, enabling surveyors to reference their local work to a broader national coordinate system. The NGS maintains these stations as permanent or semi-permanent monuments to support mapping, engineering projects, and property surveys. Verification and documentation of benchmark locations remains valuable to the surveying profession. Even as technology evolves, maintaining accurate records of established control points ensures continuity in surveying practices and provides references for validation of modern positioning methods. This station contributes to Pennsylvania's geodetic infrastructure and the broader national system.
