The global topography of the Moon is currently being regularly refined by the Lunar Laser Altimeter (Smith et al. 2010) on board the LRO spacecraft. We used the RDR (Reduced Data Records) altitude profiles from the LRO PDS release #5. 30 altimetry profiles were manually selected over the near-side Mare and 30 other over the far-side highlands.Or biter LOLA uses an original diffractive optical element to split the laser beam in five and then measure 5 altitudes values at each laser shot (Smithet al. 2010). These five measurements are organized as a cross, separated from each other by a distance of 17 m. Out of the five laser spots, we only used the laser spot #3, which has the advantage of providing altitude values on both the day and night side of the Moon (others are affected by an alignment problem that prevents measurements on the night side). The along-track point-to-point distance on the altimetry profiles is thus 57 m.
