Dictionary

Dictionary symbology is used to symbolize layers using a dictionary of symbols configured with multiple attributes. This approach is used when symbol specifications lead to many symbol permutations that would be inappropriate for unique value symbology.

With dictionary symbology, the symbolization of the features in the layer is based on one or more attributes that connect to a dictionary of rules for displaying the symbol. ArcGIS Pro supports the following symbol specifications as dictionaries: Joint Military Symbology specifications MIL-STD-2525B Change 2, MIL-STD-2525C, and MIL-STD-2525D as well as NATO Joint Military Symbology specifications APP-6(B), and APP-6(D).

Note:

The ArcGIS Pro implementations of MIL-STD-2525B Change 2 and MIL-STD-2525C share the same dictionary with a configuration property to switch between specifications.

  3. On the Symbology gallery, click Dictionary.

    The Symbology pane appears, displaying the current symbol information.

Text symbols

Text fields are used to display text symbols based on data from attribute fields. You can selectively map which attribute field maps to which text symbol in the Symbology pane.

  1. Select a feature layer in the Contents pane and click the Appearance tab.
  2. On the Appearance tab, in the Drawing group, click the Symbology drop-down menu.
  3. On the Symbology gallery, click Dictionary.

    The Symbology pane appears, displaying the current symbol information.

  4. In the Symbology pane, set the Text fields for the data to be mapped.

    For each text field, <none> can be selected in the layer field, and text will not display for that field.
