G 1306 — NGS BM0812 — Austin, US

This triangulation station is part of the National Geodetic Survey's legacy network, which forms a fundamental component of the United States' horizontal control infrastructure. Located near Austin, Texas, at coordinates 30.40917° N, 97.67417° W, this trig point served as a fixed reference for precise surveying and mapping operations across the region. Triangulation stations of this type were established to create geometric frameworks for accurate positional control. By intervisibility with other stations, surveyors could measure distances and angles to propagate coordinates across areas without direct measurement. The point's inclusion in the NGS network indicates its historical importance for regional geodetic work, land surveying, and cartographic efforts. Modern surveying professionals benefit from documenting and verifying such benchmarks, as they provide continuity with historical surveys and context for understanding datum relationships and coordinate system evolution in the locality.
