Place labels above or below a line based on a field

Summary

Instructions provided describe how to place labels above or below a line based on a field.

When labeling line features in the Maplex Labeling Engine and setting the Constraint Settings, an angle of '0' must be set for the Orientation of Vertical Labels. If the angle is not set then the labels will appear on both the right and the left of the vertical lines.

Procedure

1. Open the Label Manager.
   
   

   Note:
   Use the Maplex Labeling Engine.

   
   
2. Add a class for the features for those labels to appear above the line features
   
   

   Code:
   "SIDE" field = 'up'

   
   
3. Repeat step 2 for the features for those labels to appear below the line features.
   
   

   Code:
   "SIDE" = 'down'

   
   
4. In Placement Properties, set the 'up' label class to only display above
   the line 'at best' placement and the 'down' class to display below the
   line 'at best' position.
5. On the Labeling Toolbar, navigate to Labeling Menu > Options > Orientation of Vertical Labels and set the angle to 0.
