This triangulation station is part of the National Geodetic Survey's fundamental control network, which establishes the geometric framework for mapping and surveying across the United States. Located near Alameda, California, at coordinates 37.77154°N, 122.27697°W, this trig point serves as a monumented reference station for horizontal control. Triangulation stations of this type were historically established to provide accurate positional references for large-scale surveying projects, engineering works, and cadastral mapping. The point's location in the San Francisco Bay Area region places it within a densely developed area where such control remains valuable for infrastructure projects and boundary determinations. Verification and documentation of existing geodetic monuments ensures the integrity of the surveying network and supports continuity of spatial reference systems for professional and public applications. Current condition and accessibility information should be confirmed through the NGS database before field operations.

Is this point verified and usable for professional surveying?

This record has been community-verified 0 times. Data quality depends on the source: NGS and official national agency points are typically centimetre-accurate, OpenStreetMap survey points are metre-accurate, and GeoNames topographic landmarks (peaks, hills) are reference-grade only. Always cross-reference with the original agency datasheet before using this point for cadastral, legal, or safety-critical work.

Original source: this record was imported from ngs_public. Always refer to the original datasheet for the most up-to-date and authoritative data.
