This triangulation station is part of the National Geodetic Survey network, which establishes the foundational control points for surveying and mapping throughout the United States. Located near Austin, Texas, at coordinates 30.33681° N, 97.60243° W, this trig point serves as a reference for determining precise horizontal positions in the region. Trigonometric stations like this one are fundamental to geodetic surveys, providing astronomically or satellite-derived positions that enable accurate property boundary determination, infrastructure development, and geographic information system applications. The NGS network integrates classical triangulation methods with modern positioning technologies to maintain consistent spatial reference frameworks across the country. Verification and documentation of such benchmarks remain valuable for surveyors and engineers requiring certified control points. Regular confirmation of monument integrity and coordinate accuracy supports the reliability of derived surveys and prevents propagation of positional errors in subsequent work.
