4951 — NGS FO0329 — Albuquerque, US

This triangulation station is part of the National Geodetic Survey's network of control points that form the foundation of the United States' geodetic infrastructure. Triangulation (trig) stations serve as precisely positioned reference points established through classical surveying methods to support mapping, engineering projects, and coordinate system development. Located near Albuquerque, New Mexico at coordinates 35.08028°, -106.64972°, this benchmark contributes to regional control density in the southwestern United States. Such points are critical for surveyors, engineers, and cartographers requiring accurate positional references for property boundary determination, construction layout, and spatial data collection. Verification and documentation of existing geodetic marks remain valuable for modern surveying practices. These established control points reduce the cost and effort required for new survey projects while maintaining consistency with historical data. Proper maintenance and recovery of such benchmarks support continuity in geodetic operations across generations of surveying work.
