Hi,
I come out of my cave to present a possible alternative to the current moon textures of the latest revision.
So, a few days ago, after being frustrated with a fruitless search for a non-shaded mosaic of the Moon, I stumbled upon an amazing find - the WMS server had a full-res copy (109,164 x 54,582) of a 643nm reflectance map! This opportunity was way too good to pass up, so I took to the tedious task of engineering WMS web queries to scrape the whole map (72 tiles worth) from the web server, which I assembled into eight 27,291 x 27,291 tiles for easier processing.
I then downloaded this product and selected the 643nm, 566nm, and 415 color bands to more closely represent true color. Since the data only goes to ±60°, I had to cheat and use GIMP's sample colorize feature to color the remaining ±30° data with a palette derived from the Hapke maps. Thus, the map has a noticeable discontinuity where the real data and image trickery meet, which I've tried to reduce to the best of my abilities.
The Hapke data was upsampled and used as a coloring layer in Photoshop a la Landsat pan-sharpening, where the full-res reflectance acts as the luminosity layer. After equalizing the brightness between images, the finished tiles were resized through GIMP/ImageMagick and sent through plsplit64. Texture generation was relatively uneventful, except for the occasional "pltex ERROR; could not create temporary bitmap" that occurred at random places in the sequence. I couldn't wait to see how the final result would look in Orbiter - even level 9 was already looking amazing, but I had to stop and finish the map before I got too lost in the visuals .
Anyway, enjoy the images in the meantime!
Here the flaws of the current elevation map are put into sharp relief - any word on using the SLDEM2015 data, martins?
