A review of current selenodesic work undertaken by the French Centre d'Etudes et de Recherches Geodynamiques et Astronomiques is presented. Both photographic and occultation observations are employed in the study of the lunar limb, important for the determination of lunar position with respect to stars. It has been concluded that the shape of the moon differs from the Weimer atlas of lunar profiles to that of Watts, and a procedure has been developed to reduce one to the other. The relation between the eastern and western limbs is also under investigation, using measurements taken during lunar and solar eclipses. Chord determinations, taken at the times of the occultation and reappearance of a star, are also used to determine the distances between the eastern and western limbs. The measurement of positions of craters in various librations is being continued and the positions of all United States laser reflectors and Lunokhod 1 have been determined.
