For both the ship's current position and the planned route, the system automatically checks and generates a list of ENCs and publications required for a safe voyage. Once the purchase is confirmed, the data becomes available via a web link. Periodic updates are delivered in the same way, and the system offers two options for uploading data to the ECDIS. The first option is manual, using a CD or flash drive. The second option is automatic, via a shared folder and GET-ENC connection.
