I didn't know of existence of this study:
http://www.provisg.eu/news/First-Lunar-Reconnaissance-Orbiter-Camera-Results
http://lroc.sese.asu.edu/news/?archives/97-First-LROC-Stereo-Results.html


Where could I download the full DEM from? Which is its resolution? And above all, can I put it inside GoogleEarth? :whistle:

And does it already exist somewhere any anaglyph of Apollo landing sites, being L/R images available?

See here:

and here:

And last but definitely not least, some GIS data for the Moon. It may take a while. The file is over 4 gigabytes.

Global LROC stereo DEM? You can't, it doesn't exist. LROC images come in stereo pairs, you use a pair to generate DEM of the area contained in the pictures (there is some software which can do that, but can't remember how it is called). Of course, you must first, um, unscramble the images, as described here: http://moonscience.yolasite.com/lroc-wac.php

You can however download global DEM made with LOLA laser altimeter here: http://imbrium.mit.edu/DATA/LOLA_GDR/ Available resolutions between 4 and 512 pixels per degree (7.5km and 50m per pixel).



And above all, can I put it inside GoogleEarth?


I don't think Google Earth can read DEMs, but you can use:

- LTVT as explained here: http://ltvt.wikispaces.com/Sources+of+Planetary+DEM+Data
- Celestia: http://imbrium.mit.edu/EXTRAS/CELESTIA/
- follow my lead and use DIY approach with MATLAB/Octave: http://moonmapper.wordpress.com/2010/10/03/a-map-in-five-easy-steps/ (sorry, couldn't resist :D )

As far as I remember, Jaxa was able to build a virtual 3d model of apollo 11 landing site, and I think the resolution was up to 5-10 meters. Are those data public?

It was Apollo 15 landing site. :-) I don't know if they published the reconstructed DEM, but it was done from stereo images taken by TC (Terrain Camera). The images should be downloadable, see here: http://www.unmannedspaceflight.com/index.php?showtopic=6281&pid=149016&mode=threaded&start=#entry149016 Also, Kaguya had carried a laser altimeter (named LALT) and this dataset is for sure available (because I use it), although the resolution is much, much lower.

Looking around, I found that USGS has put up a terrain model of Apollo 15 landing site done from LRO data, see: http://www.ibiblio.org/mscorbit/mscforum/index.php?topic=2293.0
