Part 2 - Charts
This chapter mainly shows you how to install the public keys, licenses and charts, manually update chart objects, and synchronize charts.
Official vector charts produced by National Hydrographic Offices are called ENC, Electronic Navigation Charts and delivered in S-57 format. An ENC chart is encrypted to prevent unauthorized use so the user needs a permit to
install the ENC. This permit could be loaded from a USB flash memory or CD-ROM.
Any new ENC must be loaded into the system. Some parts of the charts may be date dependent, i.e., they are visible after a set date or they are visible only for a limited period, etc.

The QR-code display is necessary for quickly registering your vessel on the getenc-onboard.com website. This significantly simplifies the registration process, as you do not need to manually enter all the data. By registering your vessel, you can continue to purchase ENC charts, which are essential for accurate and safe navigation.

Installing and uninstalling public keys and cell permits are necessary for managing access to navigational charts and ensuring data security. Public keys are used for encrypting and authenticating ENC data, while cell permits provide access to specific navigational data. These actions help maintain the relevance and security of navigational charts on your ECDIS.

Public keys (SA certificates) authenticate the source and integrity of the ENC chart used in the ECDIS. Before you install a new ENC charts, confirm that the corresponding public key is installed.
Public keys can be installed from a DVD/CD, USB flash memory, etc. or from a local folder.
To install a public key, place it on selected media, press CELL PERMITS, select corresponded file (*.PUB or *.CRT) and press LOAD button. Note: The IHO public key is pre-installed in Vega ECDIS.
To uninstall a public key, select it and press DELETE button.

ENC cells are in general copy protected and therefore require permits (but some HOs deliver S-57 cells without copy protection and therefore permits are not required).
Permits can be installed from a DVD/CD, USB flash memory, etc. or from a local folder.
To install a permit, place it on selected media, press CELL PERMITS, select corresponded file (PERMIT.TXT) and press LOAD button. Note: some ENC dataset are distributed as zip files and already contain inside a PERMIT.TXT file, in this case, there is no need to pre-install it.

Installing and uninstalling ENC charts are necessary for updating and managing navigational data on your ECDIS. ENC charts contain crucial information about sea routes, coastline, depths, and navigational objects that help captains and navigators safely plan and execute voyages. The installation process allows you to add new charts or update existing ones, while the uninstallation process frees up space for new data and removes outdated charts.

Charts can be installed from a DVD/CD, USB flash memory, etc. or from a local folder. Before the installation of separate charts make sure that the permits are installed.
To install charts, place the charts on selected media, press LOAD ENC SET, select corresponded file (*.zip) or a folder with unpacked charts set and press LOAD button.
The charts update procedure is absolutely identical to the installation procedure described above. If the updates are not correctly loaded or if an error is detected during the update procedure, the user is informed and the error message displayed.

Installing and uninstalling the IHO ECDIS Charts 1 dataset are necessary for verifying and correctly interpreting the symbols used in ENCs. This dataset includes a legend of symbols, enabling users to ensure that navigational objects are accurately displayed on the ECDIS. Having the correct set of symbols is a crucial aspect for safe and precise navigational planning.

Manual update for the selected chart allows the user to make changes and updates to the ENC manually. This is necessary when prompt data entry is required, such as receiving new navigational messages or changes in maritime conditions. Thus, users can keep their navigational charts up to date, ensuring safety and accuracy in navigation.
Manual Update

Deleting the selected chart allows the user to free up space in the system by removing unnecessary or outdated ENC charts. This helps maintain organization in the chart database and prevents the system from being overloaded with redundant information, which can improve performance and simplify access to up-to-date charts.

The "Select Cell" button allows the user to choose a specific ENC cell from the list of available charts. This function is essential for focusing on a particular cell that needs to be installed, updated, or removed. After selecting a cell, further actions such as installation, deletion, or obtaining additional information about the selected cell can be performed.

The "Cell Scale" parameter displays the scale of the chart used in the selected ENC cell. The scale determines the level of detail on the chart: the smaller the scale, the greater the detail, and vice versa. This information is useful for assessing how detailed the charts are in different cells and helps in selecting the appropriate scale for navigation or analysis tasks.

The "Cell Band" parameter indicates the category or range of data to which the selected ENC cell belongs. The band may reflect different coverage levels of the chart or correspond to a specific data classification, such as a maritime zone, port, or particular area of interest. This parameter helps users to better understand what information the cell contains and how it relates to other charts or data.

The "Update Date" parameter indicates the date when the last modifications or updates were made to the ENC cell. This information helps users understand how recent the data on the chart is. Knowing the update date ensures that the chart is current and includes the latest corrections and improvements, which is crucial for accurate and safe navigation.
Update Date

The "Cell Up-to-Date Flag" indicates the status of data freshness in the selected ENC cell. This flag shows whether the chart is current and does not require updates. If the flag is set, it means that the cell contains the latest available data and meets the standards of currency for safe navigation. This helps users ensure they are using a chart that does not require urgent updates, which is important for maintaining navigation accuracy.

The "Data Server" parameter indicates the source of the charts used in your ECDIS system.
Knowing the type of data server helps users understand the origin of the charts they are using and choose the appropriate source based on navigation requirements and available updates.
- GB - AVCS Chart Collection: This data server refers to the Admiralty Vector Chart Service (AVCS) chart collection. It is an international vector chart service that provides users with access to high-quality, up-to-date vector charts developed according to IHO (International Hydrographic Organization) standards.
- PM - Primar Chart Collection: This data server is related to the Primar chart collection provided by Primar Norsk Hidrografi AS. Primar offers collections of vector navigation charts that also adhere to international standards and are regularly updated to ensure accuracy and relevance.

The "Expired Date" parameter indicates the date until which the chart is considered valid and current. After this date, the chart may be considered outdated, and its data might no longer reflect the current conditions at sea.
- For the User: Knowing the expired date helps you keep track of the chart's validity and update it in a timely manner to ensure the accuracy of navigational information and comply with safety requirements.
- For Navigation: Outdated charts may contain inaccurate data, which can lead to navigation errors and increased risk to the vessel. Regularly checking and updating charts according to the expired date helps maintain high standards of safety and navigation effectiveness.
