Z 28 — NGS CE0225 — El Paso, US

This trigonometric station is part of the National Geodetic Survey's network of control points that establish the geometric framework for surveying and mapping across the United States. Trigonometric stations, commonly called trig points, serve as monumented reference locations with precisely determined positions used to support cadastral surveys, engineering projects, and geographic information systems. Located near El Paso, Texas, at coordinates 31.80278° N, 106.54139° W, this benchmark contributes to regional geodetic control in west Texas. NGS monuments of this classification are fundamental to maintaining consistent coordinate systems across jurisdictional boundaries and enabling surveyors to tie local surveys to the national datum. Verification and documentation of such control points remain valuable for the surveying profession, as these stations anchor spatial data reliability and provide recovery opportunities should local surveys require reestablishment or validation of historical survey work.
