1/4 SEC 17 20 — NGS DO5880 — Coconino County, US

This triangulation station is part of the National Geodetic Survey's fundamental control network, which establishes precise horizontal positioning throughout the United States. Triangulation (trig) stations serve as fixed reference points for surveying, mapping, and engineering projects by providing accurate geodetic coordinates. Located in Coconino County, Arizona, at latitude 36.15075° and longitude -112.84236°, this benchmark contributes to regional geospatial infrastructure in the southwestern United States. The position's coordinates are referenced to the national datum and are essential for boundary surveys, civil engineering work, and geographic information system applications. Documentation and periodic verification of such control points ensure the integrity of surveying networks and support accurate spatial data collection. Surveyors, engineers, and GIS professionals depend on properly maintained benchmarks for coordinate reference and quality assurance in their respective fields.
