DIKE — NGS RD2912 — Portland, US

This triangulation station is part of the National Geodetic Survey's control network, which establishes the fundamental geodetic framework for the United States. Located in the Portland, Oregon region at coordinates 45.58226°N, -122.56136°W, this trig point serves as a reference for horizontal positioning and survey control. Triangulation stations function as fixed reference points for surveyors, engineers, and cartographers conducting precise measurements and mapping activities. As a component of NGS's broader network, this benchmark contributes to maintaining consistent spatial data across regional and national scales. Verification and documentation of such control points remain essential for surveying professionals, as these references ensure accuracy in boundary surveys, construction projects, and geographic information systems. The continued maintenance and availability of geodetic control information supports reliable infrastructure development and land administration throughout the survey jurisdiction.
