is there an easy way to derive the centre of a cloud of points ?
I am aware that the set of vector points (cloud of points) could be
used to stake out a polygon/boundary and use v.centroid etc etc to
derive in turn its' centroid, but I am hoping for an easier solution
.. ?

Another (very wild) guess: what about the mean of the coordinates
of the individual polygons' centroids ?

That would be great if it could be automated.
#spearfish
g.copy vect=archsites,tmp_arch
v.db.addcol tmp_arch column='x double, y double'
v.to.db tmp_arch
If this is combined with a previous step to create
individual CATs for the exclave areas while preserving the
original CAT in another column, we can successfully apply
v.to.db even while several areas share the same ID (having
the centroids xy-coordinates for all exclave-area) _plus_
