You are here: Geometric Operators > Dissolver


Dissolves area features by removing common boundaries to create larger areas. Input attributes may be accumulated.

Input Ports

  • This transformer accepts two-dimensional polygonal features, including donuts. These polygonal features are broadly referred to as polygons.
  • Aggregate input will be deaggregated by the transformer. Attributes on the aggregate feature will be propagated to its parts.

Tip: If part-specific attributes, such as areas, need to be computed and preserved, please deaggregate before dissolving.

Because aggregates are deaggregated inside the Dissolver, it is possible that the number of output features will exceed the number of input features.

  • Dissolved polygons are formed when shared edges and interior edges between adjacent polygons are removed.




The example below shows areas before and after a Dissolver transformer was used.

Editing Transformer Parameters

Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click beside the applicable parameter. For more information, see Transformer Parameter Menu Options.
