LB100

This triangulation point belongs to France's local geodetic network and represents a fundamental control station within the country's surveying infrastructure. Trigonometric stations of this class serve as primary reference points for cadastral mapping, engineering surveys, and spatial framework establishment at regional scales. Located at coordinates 49.69435°N, 5.86669°E in French territory, the benchmark's elevation data remain undocumented in available records. Such trig points facilitate precise horizontal positioning for downstream surveying operations and support the maintenance of France's geodetic datum. The point's location within the local network indicates its role in providing ground control for topographic and engineering work in its vicinity. Documentation and verification of existing benchmarks—particularly those with incomplete elevation records—remain valuable for contemporary surveyors and contribute to comprehensive geodetic infrastructure assessment. Recovery and reoccupation of such stations help maintain survey continuity and support modern positioning standards.
