[GRASSLIST:5542] Re: LIDAR Processing in Grass 5.7/Grass 6.0

[Massimiliano Cannata]

At the moment the commands are not inside the 5.7 or 6 version of grass.

The commands you are referring works with old site format (5.3), that 
has been replaced with the new vector format.
When I'll be not so busy I'll reimplement them for the new version.... 
(hope soon).

in the newer version you have to refer to v.surf.idw and no more to 
s.surf.idw.
I suppose that r.countur running time depends on the raster resolution 
you are processing......

Good by,
Maxi
