[GRASS-user] Geographic Mean

[Dave Kent]

Is the centroid of the hull equivalent to the centre of gravity of  
all the points or is it the area centroid of the hull?  Are these the  
same?

I have a similar application.  I have a series of point data with a  
numeric attribute.  I would like to get centroid weighted with  
respect to the attribute.    Can v.hull do this?

The application is a mass haul problem.  I have multiple sites each  
generating a different mass of material.  I wish to find the centre  
of generation of the set of sites.

Thanks in advance.

Dave
