RV 3 — NGS FO0250 — Albuquerque, US

This triangulation station is part of the National Geodetic Survey's network, which establishes the fundamental control framework for surveying and mapping across the United States. Located near Albuquerque, New Mexico, this trig point serves as a reference monument for horizontal position control in the Rio Grande valley region. Triangulation stations of this type were traditionally established to create precise geodetic networks through intersecting sight lines between elevated points. Such monuments remain valuable for validating modern positioning systems, conducting local surveys, and maintaining continuity with historical survey work. Surveyors and geodetic professionals rely on documented control points to ensure accuracy in land surveys, engineering projects, and spatial data collection. Verification and proper documentation of these reference points support the integrity of the National Spatial Reference System.
