Slava,

Producing S-57 files is quite involved.  The default support in ogr2ogr really
depends on you having the data already in exactly the S-57 data model.  This
can work when transforming from S-57 to S-57 but otherwise is very
very difficult.

Are you hoping to write S-57 files with ogr2ogr?  A script?  A C++ program?

I did once write a small c++ program to write files with just soundings but
I can't seem to find the source code now.  Normally a task like this would
either require a serious S-57 expert or you would need to contract someone
like me to assist and it would be somewhat expensive.

Best regards,
