Symbols to Use with Manual Updates

Manual updates can be used for the following purposes:
•
Keep charts up-to-date using similar symbols as the real chart uses. We refer to these symbols as "True
symbols".
•
Keep charts up-to-date using conspicuous orange symbols reserved for this purpose. We refer to these symbols
as "Orange symbols".
Add additional mariner information using conspicuous orange symbols reserved for this purpose.
Orange symbols are recommended because then you, your mates and pilots can easily find these symbols. Another
benefit of the orange symbols is that they are very easy to insert. However, orange symbols do not cover all
possibilities. Experienced operators can use true symbols to create their own cartography.
