Symmetrical Difference

Function Description: Calculates the geometric intersection of the input features and update features and returns the non-overlapping input features and update features. The features or parts of features from the input and update features that do not overlap will be written to the output feature class.

Data Description

Input and Output Relationships

Input and Output Relationships for Symmetrical Difference

Notes:

• The input and update feature classes or feature layers must have the same geometry type.

• The attribute values from the input feature class will be copied to the output feature class.

Steps

1. Go to Toolbox -> Vector Tools -> Overlay Analysis -> Symmetrical Difference tool, and double-click to open the tool window.

Symmetrical Difference

Parameter Description:

• Input Features: The input feature class.
• Update Features: The update feature class. Its geometry type must match that of the input feature class.
• Output Feature Class: The feature class where the results will be written.
• Add Result to Project: This option is only effective if the output feature class is saved to the gpkg database associated with the project. When checked, a layer for the resulting data will be automatically created and added to the project.
