[GRASSLIST:1305] Re: importing soil sediment data

[Helmer Schack-Kirchner]

To import the data rearrange it to the format described in
the command 's.in.ascii'. (long lat #cat %dec
.... at string...) For this purpose you may use a spread sheet
program, a column orientated text editor or, the best
solution an awk program.
With s.in.ascii you produce a site file, where all
attributes can be analysed with grass functionality. For
analysis you may interpolate to raster files or  calculate
indices with r.mapcalc ...
Best regards,
Helmer
