[GRASS-user] v.in.ascii with large files

Hi,

I see that 'v.in.ascii -help' says that we should try using the -t or the
-r flag if the data to import is too large to avoid memory problems.  I
have a pretty large bathymetry (GEBCO) data to import of ~220 Mb, so I
tried the -t flag first, and after a few minutes v.in.ascii is using huge
amounts of memory, blocking the system anyway.  I haven't tried using the
-r flag to import only a subset, which would mean import the whole file in
several calls and merge the maps afterwards.  Before I try that, I wanted
to ask what other users are doing in these cases.  Thanks in advance for
any suggestions.


Cheers,
