[mapserver-users] VRT / CSV data sources are not displayed in a layer

Stefan,

I would suspect that your .vrt file contains relative rather
than absolute paths and that they are relative to a
different working directory if used from MapServer.
There is an attribute for the <SrcDataSource> that
may address this.  It might help if you posted the
VRT.
