[STATSGRASS] krigged dem lost detail

[Carlos "Guâno" Grohmann]

Hello,

I am comparing the results we get when re-interpolating a DEM to a
higher resolution. I did it with krigging (in R, with gstat) and with
RST. In the final result it looks like the krigged DEM has lost
detail, while the RST DEM kept those.
see it:

I don't know why this happens, since they were interpolated wit the
same resolution, based on the same dataset.

thanks

Carlos
