Praktikant/in2 ARP napisa?(a):
I send you the small text file which does work with nnbathy but doesn't work with
r.surf.nnbathy after importing in GRASS with r.in.xyz
Maybe something is wrong with the text file. Or I make something wrong when
importing the xyz file in Grass.
Thanks for the sample. To reproduce your setup I also need the exact
r.in.xyz command you used to import the file as well as the region
settings where r.surf.nnbathy fails (g.region -g output).
I might be able to look into this next week.
