<P>Hi Frank,
<P>There was some problem to use the ogr2ogr under windows. The command was unable to find the datasource [Unable to open datasource ] :-( joined the commands below.
<P>I am also not quite sure how can I make sure that the dbf file contains certain columns- such as code ISO, country names, region names.
<P>.\v0soa\vmaplv0\soamafr is the relative path of the data sources</P>
<P>soamer is at the same level as dht. and lat. files<BR></P>
