BE-LU 221

This trigonometric benchmark is part of France's local geodetic network, serving as a reference point for surveying and mapping operations. Trig stations of this classification historically provided fundamental control for terrestrial surveys and continue to support modern positioning work when integrated with contemporary coordinate systems. Located at coordinates 49.97466°N, 5.82640°E in French territory, this point occupies a position in the northern portion of the country. The elevation value requires documentation through field verification. As part of the local network infrastructure, this benchmark contributes to the spatial reference framework essential for engineering surveys, cadastral work, and infrastructure development. Verification and accurate registry of such control points remains important for surveyors requiring established reference stations, particularly in regions where higher-order networks may be distant. Proper documentation ensures continuity of geodetic control for professional surveying practice.
