The French Geodesic Mission to Lapland, which took place in the 18th century, was a significant scientific expedition aimed at determining the shape of the Earth by measuring a meridian arc. Specifically, it was part of a larger effort to resolve the debate over whether the Earth was an oblate spheroid (flattened at the poles) or a prolate spheroid (elongated at the poles).
