[GRASS-user] lidar data - nnbathy x bspline

Is this dataset available? I would like to do some test too. Although, 
those are intrinsic features to the interpolation method (dividing the 
whole zone into smaller regions) and shaded relief maps (as aspect 
maps), I'm afraid, I was wondering whether they could be reduced.

If this is not possible, I'll try to give you a better explanation about 
why they are produced.

Regards,
Roberto.
