We are updating the elevation map background for the Moon, from #LOLA data -- using a diverging colormap with smoother colors that should be better to overlay footprints, and completing the north/south latitudes with data at 118m/px.
Mercury also get an elevation background! Using the same colormap and the USGS #MDIS produced global elevation dataset -- its resolution will leave to be desired when zooming a bit, but it is helpful nontheless.
