right, but it still remains a system created for the automatic recognition
of features in 1:100.000 with generalized areas (min 25ha), for Europe. It
is not helpful for our purpose.
If you are interested in reading some interesting thoughts about landcover
classification, there is the FAO landcover classification system, thought
to be useful globally:
http://www.fao.org/3/X0596E/X0596e00.htm

One interesting find is the rejection of the term landcover for bare soil
for purists (and then admits they are usually contained) ;-)
