[GRASS-user] v.vol.rst : doubts about parameter "zmult"

[Eduardo corbelle]

Hello list:

I've been working recently with v.vol.rst and I have doubts about
the real function of the parameter "zmult": the manual says it allows
the user to re-scale (change units of) the z coordinates of the data; but
I obtain better results when using high values (about 20) of zmult even if
no unit
transformation (re-scaling) is needed at all (all data in metres). Could
anyone give me a
hint on the actual role of zmult in the interpolation process? Is it
reasonable to use "very"
high values (e.g. 100)?

Thank you very much
