Transform dialog

The transform dialog is used in a number of places where information needs to be prepared, manipulated or processed during import, copying or export.

Transform

The Transform table lists the attributes that will be generated when creating your new features.

The table provides the following information:

  • Attribute: name of the attribute being generated
  • Type: type of attribute being generated. This value is calculated on the fly as you enter a expression.
  • Expression: expression used to calculate output values

Add

Up

Down

Remove
