[GRASS-user] r.contour

[Frank Aragona]

I've used r.contour to create my contour map from an interpolated 3D 
surface.  However, the level category in the attribute table shows 
values y coordinates from xyz, not the z coordinates.  What gives?  How 
do I tell grass to use the z coordinates when doing my contours?  I 
don't find this in the documentations.  Or did I interpolate my surface 
incorrectly?
