Select an object from the list.

Fill in the object properties and attributes.

In the main window, the ENC cell being updated will be highlighted with a blue frame.

5. Add attributes

Press to open the attributes list.

• By entering coordinates — enter exact coordinates manually

Tip

Object points can be placed on the chart using the cursor, then adjusted in the input fields.

Enable/disable the Display on chart checkbox to show the object on the chart.

The object will be displayed on the chart, within the scamin attribute limits.

Save the object.

Important

Manual update history for the selected cell will be reflected in the History. Making changes to an update object is treated as a new update.

Analyzing received automatic updates for matches between manual and automatic updates is the responsibility of the navigating officer.

All manual updates are reflected in the ENC collection report.

Manual update features

• Delete — remove objects from the chart

History and reporting

All manual update actions are recorded:

• All changes are logged in the update history

• Changes are reflected in the ENC collection report

• Searching and filtering by dates and cells is available

Interaction with automatic updates

When working with manual updates, interaction with automatic updates must be considered:

• The navigating officer is obliged to analyze matches between manual and automatic updates

• If discrepancies exist, a decision on priority is required

Warning

Manual update is an official document and must correspond to information from Notices to Mariners. If discrepancies with automatic updates are detected, an analysis must be conducted and a justified decision made. Priority should be given to automatic updates.

Tip

It is recommended to keep detailed records of applied manual updates, including the information source (Notice to Mariners number and date), the date of application, and the responsible person. This simplifies subsequent analysis and verification of updates.
