This triangulation point is part of a local geodetic network in the Netherlands, situated near Vierpolders in South Holland at coordinates 51.89934°N, 4.17188°E. As a trig station, this point served a fundamental role in establishing horizontal control for regional surveying operations and mapping activities. Local networks such as this provided essential reference geometry for cadastral surveys, infrastructure projects, and land administration across Dutch municipalities. The triangulation method employed at such stations enabled surveyors to extend positional control across the landscape through intervisible point networks. While the elevation value remains unrecorded in available documentation, verification and proper documentation of such benchmark locations remain valuable for understanding historical survey frameworks and maintaining geodetic continuity. Current coordinate systems benefit from knowledge of these foundational reference points.
