Information required on World Data from Moon

[MSC9309 at geovax.ed.ac.uk]

Hi,

One of my colleagues here has been working with some data sets derived
from the grass4.1/release/world directory on the FTP site moon.  He has read 
the document describing the global data set, but is still not entirely sure
as to how the aspect data set was devised.  The document says it was produced
using r.slope.aspect, so this indicates there is some elevation data that was
the basis.  Does anyone know where this came from, and the scale, resolution
or anything about it?

Cheers, 

Dave H.
