<br>Nikhil, <div><br></div><div>There is no OGR API level way of knowing what S-57 updates are changing. They basically get merged into the feature view giving you a "final result" view through OGR. If you really need to track this you pretty much have to open variations on the S-57 datasource with and without the updates. </div>
<div><br></div><div>If you are just debugging, it is often instructive to run 8211view on the update files. </div><div><br></div><div>Best regards,</div><div>Frank</div><div><br><div class="gmail_quote">On Thu, Oct 11, 2012 at 11:26 AM, Nikhil Sai Parupalli <span dir="ltr"><<a href="mailto:nikhil.parupalli@iictechnologies.com" target="_blank">nikhil.parupalli@iictechnologies.com</a>></span> wrote:<br>

US1GC09M.000 <-- base cell<br>
<br>
<br>
