Map of France. Historical map of France after a resurvey of the 1680s. The improved profile is seen in dark shading over the lighter shading of the previous map. The resurvey was ordered by King Louis XIV and was carried out by triangulation by the astronomers J.D. Cassini and J. Picard. The king then complained that the scientists were shrinking his territories. Image from Memoires de l'Academie Royale (1729).
