With the help of User Layer
editor a navigator may add his own object and comments as an overlay to an ENC.
This function may be used for adding specific information to a chart, textual
notes or for temporary chart correction. It is possible to add the following
types of objects:
-
areas of any complexity;
-
lines;
-
symbols;
-
texts.
The user may select color,
footprint as well as orientation and size (for symbols and texts), fill color
and pattern (for areas and lines).
User objects are grouped into a
number of User Layer's according to the operator choice. Initial cartographic
data remains unchanged.
In contrast to manual
chart updating, the information about user's objects is used only for
information display - the system does not use this information in navigation
safety tasks.
