Labels sublayers give you the possibility to label each
vector layer differently. For example, the labels can be:
In addition, it is important to distinguish the visible
differences between road, motorway, and state or county labels to
make the map more readable. You can do this by setting the font size,
fill color, whether the outline is drawn, and if so what the outline
color will be. See
Using the map style property sheet and
Setting sublayer properties for
more information on how to use the Property Sheet.
Each time you set the Labeling
property
for a displayed data source containing label information, a Labels for: sublayer is created in
the Map Layers pane under the Labels layer. You can then specify the
style of labeling for each Labels sublayer using the corresponding
Property Sheet.
The order of the Labels sublayers in the hierarchy defines
the priority of the labeling. When the labeling is performed, the
labeler places as many labels as possible on the first layer in the
hierarchy, and then considers the placement of labels on the next
Labels sublayer, and so on.
You can then specify the priority of the labeling by
reordering the Labels sublayers. This enables you to distinguish between
the labeling layers more easily and prevent the view becoming too
complex. Note that the layer with the highest priority is situated
at the bottom of the stack.
The following figure shows an example of customized Labels
sublayers.
