5 Chart Editing 5-2
This chapter describes how to create user maps and how to manually update charts.
User Map
User map can be created and displayed on other charts. User map information contains various objects
(symbols, lines, areas, and texts). User map can also be edited and updated. Also, you can merge
multiple maps together to create one user map.
The following figures show how to use user map:
Example 1:
Example 2: Example 3:
How to Display the User Map:
To display the user map, see 3.10 “Displaying a User Map”.
In the normal menu
Select [MENU] - [(5) User Map] - [(1) Select User Map] in the order.
Manual Update
Objects (symbols, lines, areas, and texts) can be manually updated. When you save data after
manually updating the objects, there will be a panel for you to enter the issue date of a notice to mariners.
Enter the date. You can check the issue dates of a notice to mariners by using S-57/C-MAP/ARCS
information.
Unlike User Map Edit operation, Manual Update operation links objects directly to the chart. Therefore,
the objects updated manually in the chart cannot be deleted as desired, but can only be hidden from the
chart. For the method of hiding the objects, see 5.5.3 “Hiding Objects (Only during the Manual Update
Operation)”.
When all the following conditions are met, objects updated manually are deleted automatically from the
chart.
• The chart having objects updated manually has been updated in Chart Portfolio.
• 3 months or more have passed since the chart was updated manually.
• The objects to be deleted are hidden from the chart.
Note:
• C-MAP charts cannot be updated manually.
• The objects updated manually in S-57, S-63 or ARCS chart can be used commonly in those charts.
You can merge as
one user map.
