That's the arithmetic mean. The geometric mean of a set of N values is the Nth root of the product of the values (i.e. the logarithm of the geometric mean is the arithmetic mean of the logarithms of the values). It wouldn't be meaningful to compute the geometric mean of coordinate data. -- Glynn Clements <gl...@gclements.plus.com> _______________________________________________ grass-dev mailing list grass-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-dev
