A 1009 — NGS AW1820 — Harris County, US

This triangulation station is part of the National Geodetic Survey's network, which establishes fundamental control points for surveying and mapping across the United States. Triangulation (trig) stations serve as precisely positioned reference points from which surveyors establish local coordinates and conduct detailed surveys. Located in Harris County, Texas, this benchmark contributes to regional geodetic infrastructure in a densely populated area of the Gulf Coast. The coordinates 29.95944°, -95.68361° define its position within the national spatial reference system. Verification and documentation of such control points remain essential for surveyors, engineers, and cartographers. Maintaining accurate records ensures reliable measurements for land surveys, infrastructure projects, and mapping applications. Regular confirmation of benchmark stability and coordinates supports the integrity of surveying operations across the region.
