I'm looking for a reflectance map of the Moon to use in 3D visualization software. I've found NASA's CGI Moon Kit, which is described as
These color and elevation maps are designed for use in 3D rendering software.
This map is based on data from LROC. The Moon Kit also contains elevation data, which I can transform to e.g. a map of normals for bump mapping.
It looks like exactly what I need, if not one problem: this reflectance map only covers 70°S to 70°N. The polar regions are filled with useless (Photoshop-generated) texture. They explain it thus:
The source data covers the lunar globe from 70°N to 70°S. Because the Moon's axial and orbital tilts are both small, many areas outside these latitudes remain shrouded in shadow, even after thousands of passes by LRO's camera, so they are left out of the LROC mosaic.
OTOH, in another blog post, A Unique View Of The Moon, the data from that same LROC appear to be much more complete in terms of latitudes covered, but I've not found where to download this processed map (even if only for 643 nm, as said there). I've only found the large TIFF version of the view of the reflectance of the near side, mapped to a sphere (at the end of the post), and a rotation movie of this sphere, both of which are not too easy to convert to a final global texture.
Yet another NASA blog post, Synthetic Views of the Moon, appears to use the same LROC WAC reflectance map as the one mentioned above, but produces the look of the Moon in color, so apparently the reflectance map there is not for a single wavelength already. Still, it only shows the image produced, but doesn't give any links to actual reflectance map.
So I wonder, where can I download the full reflectance map to be able to reproduce these and create other images of the Moon? Is it available to the general public? Maybe I've missed some link in the posts I was reading?
