I saw this some months ago. You can purchase the data IIRC for £30 or you have to subscribe. As you mention, the abstract (it was a scientific paper) is not very clear on the nature of the improvement, the error parameters and the form in which the data is provided. I need raster map images to insert into AutoCad.The discrepancy I found between the South Massif's height in the photo and it's height on the NASA contour map is so enormous (1080m), I felt repeating the work with the Chinese map (if you actually get access to maps by purchasing the Paper) would be a waste of my time and unlikely to produce a significantly different result. To put the results of my analysis in simple terms ground level at the lander is 4690m, the peak of the "fake painted backdrop" South Massif in the photo is 3656m higher than the lander, whereas, according to the contour map it should be 2374m higher ie it appears ~50% higher than it should do.
There are a number of NASA liar "spoofs" on YouTube trying desperately to prop up the "Man on the Moon" myth. I've had encounters with a few of them eg knowledgemonger, spreadingthemuse and ytmoog. I'll put up a few posts later illustrating some of their desperate failed attempts to refute my analysis ....lol http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=5783918
