ISLE — NGS RD2323 — Camas, US

This triangulation station is part of the National Geodetic Survey's network of control points that form the foundational framework for surveying and mapping across the United States. Located near Camas, Washington, at coordinates 45.57215° N, 122.43859° W, this trig point serves as a reference monument for establishing horizontal positions with high accuracy. Triangulation stations like this were historically observed and connected through sight lines to other monuments, creating a web of known positions used for precise surveying work. Modern surveyors, engineers, and cartographers rely on documentation and verification of such benchmarks to ensure accurate spatial reference data for construction projects, property surveys, and geographic information systems. Maintaining complete records of these control points, including their location, condition, and accessibility, remains valuable for the surveying profession and contributes to the integrity of the National Spatial Reference System.
