Z 1500 — NGS AC6333 — Harris County, US

This triangulation station is part of the National Geodetic Survey's extensive control network that forms the foundation of horizontal geodetic reference throughout the United States. Located in Harris County, Texas at coordinates 29.91417°N, 95.37583°W, this trig point serves as a reference monument for surveying and mapping operations requiring precise spatial positioning. Triangulation stations of this type were established to provide surveyors, engineers, and cartographers with reliable reference points for large-scale projects including land surveys, infrastructure development, and geographic data collection. The NGS network continues to support professional surveying practice and maintains the geometric framework underlying spatial databases and cadastral systems. Verification and documentation of benchmark locations such as this remain valuable for surveying professionals conducting boundary work, establishing control networks for construction projects, and validating positioning data. Proper identification and perpetuation of these reference monuments ensures continuity of survey standards and accuracy across generations of surveying work.
