Replying to [ticket:2500 martinl]:
> Do we need the both modules in G7?
* could they be merged?
* or one of them moved to addons
Even if they could be merged, it would require some work and time. So
based on the r.surf.idw manual page:
{{{
r.surf.idw will generally outperform r.surf.idw2 except when the input
data layer
contains few non-zero data, i.e. when the cost of the search exceeds
the cost of the additional distance calculations performed by
r.surf.idw2.
The relative performance of these utilities will depend on the
comparative
speed of boolean, integer and floating point operations on a particular
platform.
}}}
and r.surf.idw2 manual page:
{{{
Another surface generation program, named r.surf.idw,
should be used with latitude/longitude data bases
}}}
I would move r.surf.idw2 to addons. But I don't think I was trying any of
them.
