Dataset Legend : Labels

Legend Editor > Labels

Activate labeling and its options “Resolve Collisions” and “Dynamic Positions”.
Select the attribute of which its value needs to be displayed.

Some data formats (like *.ovf and *.ovt) may support multiple values for one object attribute. If so, only the first value will be displayed.

Labels may overlap each other. The option “Resolve Collisions” will hide a label if it overlaps another label. Calculating overlaps may take some time, it is advised to use this option in combination with Layout Scale Range Limits to avoid slow map rendering.

No Collision Resolving	Resolve Collision

Labels are displayed referred to the center of the entire object which might be outside the current Map view. The option “Dynamic positioning” will re-position the label in the center of the on Map view visible part of the object.

Absolute (horizontal)	Relative	Curved

Set the relative position of Object and Label and, if not centered, its offset. Default the label is placed in the object's center.
