LB105

This trigonometric benchmark represents a local geodetic network control point situated in France at coordinates 49.71129° N, 5.88388° E. As a trig point, it served as a horizontal reference station for surveying and mapping operations within its regional network. Such points are fundamental to establishing accurate positional control for cadastral surveys, engineering projects, and cartographic work. The elevation data for this station has not been recorded in available documentation. Local networks of this type typically supported detailed surveying at departmental or municipal scales, complementing France's national geodetic framework. Given the position in northern France, the point likely contributed to regional mapping and infrastructure projects. Verification and proper documentation of benchmark positions remain essential for surveyors requiring reliable reference data. Recovery and confirmation of such points' current condition and accessibility support ongoing professional surveying activities and historical geodetic research.
