[GRASS-user]Re: Problem with v.vol.rst and 3d-interpolation

[butzeck at web.de]

Hello,


I ask Helena and she gave me the anwser. You have to use a parameter "zmult" with v.vol.rst (I try some values between 180 and 10 and choose zmult=50 for my question) . How to use "zmult" is not described in the help until now.

Regards.
