Copernicus+contour

Below, a topographic map with contour lines overlaid upon (it is also possible to overlay the contours on, say, a naturally-viewed lunar surface, or any lunar-related surface data + vice-versa). Please note, the red contour lines do not correspond to the 'legend' elevation levels, but merely serve here as a colour for the contour description. That said, it would be possible to simply apply such a contour colour to a certain elevation, that would serve as an average elevation of sorts.
