LB249

This triangulation benchmark is part of a local geodetic network in France, positioned at coordinates 50.03632°N, 5.85611°E. As a trig point, it served historical surveying operations by providing a precisely established horizontal reference for regional mapping and control networks. Such monuments are fundamental to cadastral surveys, engineering projects, and geodetic datum realization. The point's elevation remains undocumented in available records. Local trig networks of this type typically supported detailed topographical work and infrastructure planning across French territories. Though the immediate surroundings are not specified, verification and documentation of such benchmarks remain valuable for understanding historical survey networks and validating coordinate transformations between modern systems and legacy datums. Surveyors undertaking work in this region should note the limited metadata available and conduct appropriate reconnaissance to confirm the point's current condition and accessibility.
