| The New ADMIRALTY Notices to Mariners Tracings | https://www.admiralty.co.uk/news/blogs/the-new-admiralty-notices-to-mariners-tracings | On the 10th of July we changed the way our Notices to Mariners Tracings are produced. This blog takes you through these changes to help you ensure your charts are up-to-date. | | The New ADMIRALTY Notices to Mariners Tracings | 2017-07-09T23:00:00Z | How to update charts using our new Notices to Mariners tracings | <p class="admiraltyElement-P">ADMIRALTY Notices to Mariners (NMs) are designed to help you update your ADMIRALTY Standard Nautical Charts (SNCs) and ensure they contain the latest safety critical information.</p><p class="admiraltyElement-P">Our NM tracings are a key part of this service as they allow you to quickly pin-point the position of any updates and accurately apply them to your nautical charts. On the10th of July we released a new tracing style that will make these updates easier to understand and apply to your portfolio of charts.</p><p class="admiraltyElement-P">
<br>
</p><p></p><h2 class="admiraltyElement-H2">How have the latest Notices to Mariners Tracings changed?</h2>
<br>
<p>We have changed the way we present updates on the tracing itself. For example, all information that needs to be inserted will now be shown in its exact position, rather than appearing in a box and arrowed in. Below we've included examples of these changes.</p>
<br>
<p></p><h3 class="admiraltyElement-H3">Delete</h3>
<br>
<p class="admiraltyElement-P">All information that needs to be deleted will be shown with double strike throughs alongside a deletion symbol. Previously this information may have been boxed or hatched.</p>
<br>

<br>
<p class="admiraltyElement-P">All information that needs to be inserted will now be shown in its exact position on the tracing in relation to the chart. Previously this information was boxed, with its position shown as a small circle with a dot at the centre.</p>
<br>
<p class="admiraltyElement-P" style="text-align:center;"> <img src="/SiteCollectionImages/Blog%20Images/Tracings%20Blog/Insert_v01.jpg?RenditionID=9" class="admiraltyStyle-lightbox admiraltyImage-contentImages" alt="" style="margin:5px;" /></p><h4 class="admiraltyElement-H4" style="text-align:center;">An example of information that needs to be inserted</h4><p></p><h3 class="admiraltyElement-H3">Replace or Amend</h3>
<br>
<p class="admiraltyElement-P">Any new features will now be shown in its true position on the tracing and will be accompanied by the words 'in lieu'. Previously any information that needed to be amended would have featured a double strike though with new information arrowed 'in lieu'.</p>
<br>
<p class="admiraltyElement-P" style="text-align:center;">

<br>
<p class="admiraltyElement-P">Any information to be moved will be shown in its new position with an arrow drawn from its existing position.</p>
<br>
<p class="admiraltyElement-P" style="text-align:center;">

Below, we outline what each of the standards mean and why they're so crucial to safety of ships at sea.</p><p class="admiraltyElement-P"></p><h3 class="admiraltyElement-H3">What is S-57? </h3>
<br>
<p>S-57 is the data format used for the transfer of digital hydrographic data between national hydrographic offices and for its distribution to manufacturers, mariners and other data users. </p><p>Within this standard, the S-57 ENC product specification defines how hydrographic offices will construct an Electronic Navigational Chart. By meeting these specifications hydrographic offices will ensure that all electronic charts contain all the chart information that is necessary for safe navigation.</p><p></p><h3 class="admiraltyElement-H3">What is S-58?</h3>
<br>
<p>S-58 sets out validation checks that must be performed on ENCs by hydrographic offices before they are released to the mariner at sea. These checks include tests to ensure that there are no irregularities in an ENC that could cause an ECDIS to malfunction. Irregularities could include incorrectly intersecting geometry, depths plotted on land or railway tracks appearing in open water.</p><p> </p><div class="admiraltyElement-videoOverlay" style="font-style:normal;font-weight:normal;font-size:16px;font-family:"johnston itc w01 medium", arial;">

<br>
<p>This standard covers three important areas:</p><ul><li><p class="admiraltyElement-P">Piracy Protection - to prevent unauthorised use of data by encrypting the ENC information. </p></li><li><p class="admiraltyElement-P">Selective Access - to restrict access to ENC information to only those cells that a customer has been licenced for.</p></li><li><p class="admiraltyElement-P">Authentication - to provide assurance that the ENC data has come from approved sources</p></li></ul>
<p>For the mariner, this means that data which meets these standards is authenticated and comes from an official source, reducing the risk of using inaccurate data that is posed by unofficial ENCs and the risk of malware being introduced to a ship's IT systems. </p><p></p><h3 class="admiraltyElement-H3">What is S-52?</h3>
<br>
<p>S-52 is a standard used by ECDIS manufacturers that determines how ENC data is displayed on an ECDIS screen through symbols, line styles, colours and other visual cues. This means that what the mariner sees on the screen is displayed in the same way across all approved makes and models of ECDIS. </p><p>The presentation library is an important part of this standard and ship owners are now expected to update to the latest library (4.0) by August this year.
