    initial v1  
    1 '''Comment only''': Any solution is generated, I've realized that in V7 r.surf.id eats much more memory than in 6.4. Addition of FCELL and DCELL is handy, but I'm afraid that it may lead to further memory footprint growing. I'm ready for testing, anyway any new version. I use r.surf.idw extensively on huge sparse rasters where it takes 2 - 10 GB RAM to create the result.

    34When it is about an FCELL source my workaround is creating a temporal CELL coverage with mapcalc and multiplication and rounding original values and when idw is done I calculate it back to an FCELL and remove the temporal map.
