This tool is responsible for combining the polygon layers selected by you based on the selection tool chosen.

The Union tool can be selected by navigating the following path:

  • Tools > Vector Processing > Spatial Analysis > Union

The first section requires you to select required data layers to run the Union tool.

  • Select a Polygon Layer – Layer on which you will run this tool.
    Restriction: A minimum of two polygon layers must be selected to run this tool.

The second section requires you to select the range of data for the operation to be implemented. There are three options available:

  1. Select By Data Queries
  2. Select By Graphics
  3. All Data

For more information about these options and how to implement them, see Data Selection Methods.

The output is represented as a single polygon generated by combining the input polygon layers.

Note: The layers are considered to be non-contiguous if they do not share a common boundary. As a result, a Multi Polygon feature is created as the output.

You can view the output after storing it. To save the output, you must enter the Output Layer Name and click on Save Data button. The saved output will be added as a new layer in the current map session, where you can apply styling as required. This output layer will also be available in 'My Data' section and can be used in any map session of interest.
