NM 500 1 — NGS FO1275 — Albuquerque, US

This triangulation station is part of the NGS network, which establishes and maintains the National Spatial Reference System across the United States. As a trig point, this benchmark served as a primary control station for geodetic surveys, providing precise horizontal positioning data essential for mapping, boundary determination, and large-scale engineering projects. Located near Albuquerque, New Mexico at coordinates 35.02705°, -106.70474°, this point contributes to regional survey control in the Rio Grande valley area. Trig stations of this type were typically established on elevated or prominent terrain to facilitate intervisibility with other control points, creating networks of measured distances and angles. Documentation and verification of such benchmarks remain important for surveyors and geospatial professionals. These reference points provide continuity for modern positioning methods and serve as historical records of geodetic methodology. Current coordinates and condition assessments help ensure the ongoing utility of the national control network.
