ECDIS (Electronic Chart Display Information System) is an advanced navigation system that improves safe navigation at sea. ECDIS has become a must-have system on most ships depending upon the type of the ship and its tonnage.
As technology grows, electronic navigation charts (ENCs) charts have replaced paper charts over the years due to their superiority, ease of use, convenience, and functionality. That said, paper charts are still used in areas that are yet to be covered by vector charts. When navigating through such areas, it is imperative to have up-to-date paper charts as a back up option.
The real-time position of ships is often integrated by ENCs that are programmed to automatically work with chart displays to provide continuous monitoring of the vessel's position and safety. As such, the navigator can have a clear picture of the ship's instantaneous situation, and all charted dangers to smooth sailing. For the ECDIS to be used effectively, the navigating officers should not only have a good understanding of how the system works but also know how to order the charts on the specific route. They should also be aware of all means and methods available to keep the charts updated.
Electronic charts and paper charts perform similar functions but also differ in a number of ways. For instance, electronic charts are acquired after approval and permits provided by the relevant authority. The permission allows for certification and proper use of the charts. Whereas paper charts are purchased once and replaced or canceled over a given time. Licenses for electronic charts are governed by permits hence legally used to direct the vessel in the sea.
Unlike paper charts that had to be ordered and corrected before the cruise, electronic charts are more efficient and readily updated. That is, chart cells are activated after acquiring the permit typically through sending an email to the provider. The ENCs are often provided by distributors working with the national hydrographic authority under the authorities of the International Hydrographic Organization (IHO).
Step 1: Routes can be manually created or automatically created via Auto-Routing.
Step 2: To use the auto-routing; all you need to do is right-click on a port and select "Auto-route from."
Step 3: To finish the route right-click on the end port and select "Auto-route" to.
Step 4: The automated routing is limited to ports that are in the Auto-Routing system. This keeps expanding, but you will not find all ports here. The routes it creates are, however, updated by actual mariners and will automatically update. Routes done this way can only go between 2 ports.
Step 5: Once the route has been created via Auto-routing, you can always edit the route by right clicking on it and selecting any of the options that appear on the screen. You can also drag and move the waypoints on the screen by left clicking on a waypoint and dragging it to the new point you'd like the waypoint to be at.

Step 2: In this example, we will create order from Port Said to Palermo.
Step 3: Once you have the route right-click anywhere on the red line and choose to get charts.

Step 9: Once happy with the list of cells needed, you have three options:
Step 10.1: Request Online: use this if your viewer is online connected and able to connect to the servers, once the order is successfully sent, you'll see below information;
Step 10.2: Save as File: gives you the option to save a basket file and send this for firstname.lastname@example.org once Save as File is clicked you get below information:

Step 1: After your AVCS ENC order has been approved by your distributor you can download your AVCS charts in SPICA by clicking on the yellow button that says Update Charts in the charts section of SPICA. Weekly ENC updates can also be downloaded by clicking on the yellow button Update Charts if there are updates available to download.
Step 2: After the download of AVCS ENC charts is complete click on the tab Export for ECDIS to export the AVCS ENC charts to a USB or CD. Once your ENC charts and permit files are saved to your removable media take it to your ECDIS to upload the ENCs.
Keeping the ECDIS fully up to date should be a high priority for the bridge team to ensure safe navigation and should be treated as equally important as normal paper chart corrections. It is important that the responsible navigating officer check the expiration date of all permits/licenses and to record them, to avoid unplanned and dangerous situations such as losing the chart’s display in the ECDIS.
