LV 3 — NGS CE0509 — El Paso, US

This trigonometric station is part of the NGS network, which establishes the fundamental geodetic control framework for the United States. Trig stations serve as precisely positioned reference points essential for surveying, mapping, and engineering projects across diverse landscapes. Located in the El Paso, Texas area at coordinates 31.71377°N, 106.37194°W, this benchmark contributes to regional spatial reference infrastructure. Such control points enable surveyors and geodetic professionals to establish local surveys with known accuracy relative to the national coordinate system. Verification and documentation of these monuments remains critical for maintaining the integrity of surveying networks. Modern applications including GPS surveys, GIS databases, and construction projects depend upon the accessibility and reliability of established control points. Regular inspection and recovery efforts ensure these reference marks continue serving their essential role in geodetic science and applied surveying practice.
