[Jason Pickering <jason.p.pickering@xxxxxxxxx>]

To add to Brams mail, I have had issues with MapShaper and the DBF's it
produces. Normally, I just trash these, and use the original DBF from the
unmodified shapefile.

I am still not convinced it is a problem with the DBF though, as clearly
the projection which you provided in the first conversion was not correct.

Regards,
Jason
