#2671: r.surf.idw won't make interpolation
------------------------+---------------------------------------
Reporter: kuszinger | Owner: grass-dev@…
Type: defect | Status: new
Priority: normal | Milestone: 7.1.0
Component: Raster | Version: svn-trunk
Resolution: | Keywords: interpolation, r.surf.idw
CPU: x86-64 | Platform: Linux
------------------------+---------------------------------------
Comment (by neteler):
The indicated test is now performed as follows:
{{{
# GRASS 7.1.svn (nc_spm_08_grass7)
g.region raster=elevation@PERMANENT -p
r.random -z --overwrite input=elevation@PERMANENT npoints=100000
raster=elev_sparse
r.surf.idw --overwrite input=elev_sparse output=elev_sparse_idw npoints=7
ERROR: This module currently only works for integer (CELL) maps
}}}
So, no result should be expected unless #2672 is solved.
Replying to [comment:6 annakrat]:
> I think I fixed it in r65214. Null values were not identified correctly.
I still don't understand why 64 version actually works.
Backported in r65261.
> By the way, r.surf.idw works only with integer rasters. But this is for
a different ticket.
Closing here, continuing in ticket #2672
