NGS Triangulation Station, Alameda County vicinity, California. This trig point comprises part of the National Geodetic Survey's classical triangulation network, which established the foundational control framework for large-scale surveying and mapping across the United States. Positioned at 37.77242°, -122.28813°, the station serves as a precisely located reference for geodetic and surveying operations throughout the region. Trig stations of this network type were typically established through intervisible observations to create networks of known positions. Such benchmarks remain valuable for modern surveyors, engineers, and GIS professionals verifying local coordinate systems and validating contemporary positioning technologies. Documentation and verification of these historical control points helps maintain the continuity and reliability of the nation's geodetic infrastructure and supports quality assurance in surveying practice.

Geodetic context in United States

The national geodetic reference in United States is maintained by National Geodetic Survey (NGS). The active datum is NAD83(2011) / NATRF2022 (active). Coordinates shown on this page are expressed in WGS84 (ETRF/ITRF-compatible) which is directly usable in most modern GNSS receivers. For cadastral work in United States you may need to convert to the local datum using the Coordinate Hub.
