[GRASS-user] clear sky index interpolation

[buraq]

Hi again,
Actually I want both.
I ran like this "v.surf.rst input=KcVect elev=KcRast zcolumn=kc tension=10
segmax=600" It is ok and no problem here. Problem starts at 3D volume.
 Now my csv contains {lat,lon,elevation,kc}. When I try to run v.vol rst I
get that "Error in COGRR!" "Interp_call failed".
