[Gstat-info] Re: gstat bug?

[Edzer Pebesma]

Thanks, that clears things up, Thomas.

The gstat -e convert business is rather old and, if I may say so, 
obsolete these days. The usage is given by:

edzer at edzer-vaio:~/S/test$ ~/cvs/gstat/src/gstat -e convert
Minimal map converter (topology and cell values only)
usage: convert [options] in_map out_map
options:
        -f [type]
        -h   print help
target types supported:
        a gridascii
        b idrisi binary
        d Surfer DSAA
        e er-mapper
        f gridfloat
        g GSLIB
        i idrisi ascii
        n GMT/netcdf

meaning that a meaningful usage would e.g. be

gstat -e convert -f a in_map out_map

converting in_map (grid map in readable format) to gridascii format. So 
there are two problems: (i) you don't use the -f option with argument, 
(ii) your input file is not a grid map.

Today, for converting between grid map formats I would advice to use 
ogr2ogr.
