The topography of the Moon referenced to the lunar geoid. The topogographic model is derived from the spherical harmonic model <a rel="nofollow" class="external text" href="http://www.ipgp.jussieu.fr/~wieczor/SH/SH.html">USGS359</a> (dead link, compare <a href="//doi.org/10.1016/j.epsl.2012.02.012" class="extiw" title="doi:10.1016/j.epsl.2012.02.012">doi:10.1016/j.epsl.2012.02.012</a>), and the lunar geoid was obtained from the gravity model LP150Q. The color coded topography is overlain on a shaded relief map.
