Labeling List Objects

This mode is intended for labeling list objects by semantic characteristic.

To label a list:

1. Enable the Label Objects mode.

2. Select a semantic characteristic. By default, the Proper Name semantics is set. When hovering over the semantic code, the name of the semantic characteristic is displayed in a tooltip.

Semantic selection is performed by left-clicking the mouse in the semantic code display area. In the Select Semantics dialog, choose the required semantics for labeling.

If the selected semantics is absent in the object being labeled or has no value, this object is not labeled.

The label appearance can be set by default, with color replacement, as for a thematic layer. Alternatively, it can have a custom appearance. This is configured in the Edit Styles mode. When changing the semantic code, color, or label appearance, the list of objects is relabeled. Simultaneous display of list objects with conventional symbols and labeling by semantics is available.

When the Dynamic Labeling checkbox is disabled, automatic labeling of the entire map is performed. The labeling result is recorded in a temporary map displayed on top of the original map.

When the Dynamic Labeling checkbox is enabled, automatic labeling of the map within the window is performed. Labels are placed so that they fit entirely within the window area and do not intersect point and line objects of the labeled map. If there is insufficient free space, dynamic labels may slightly intersect line objects. If significant intersections affecting label readability are detected, object labeling is not performed.

When the Advanced label intersection analysis checkbox is enabled, intersection analysis of the created label is performed with point and line objects of all document maps. If the checkbox is disabled, label intersection analysis is performed with objects of the map on which the labeled object is located.

Example of dynamic labeling of object lists

The labeling order of list objects is configured in the General Data List tab in the Map Legend, which opens in the right part of the application window when selected from the main menu: Tasks → Map Legend (F11).

The figure shows the list of displayed maps (1, 2) and the layers of labeled object lists (List5 [1], List4 [1], List1 [2], List2 [2], List3 [2]). The square brackets indicate the names of the maps to which the object lists belong. Layers located at the top have the highest priority. Objects of the "List5 [1]" layer are labeled first, and objects of the "List3 [2]" layer are labeled last.
