Swaps coordinate axes of the input features.


Usage Notes

There are three common uses for this transformer:

  • The transformer was originally intended to help solve the problem of Lat/Long order, where some formats expect Latitude/Longitude, and others expected Longitude/Latitude.
  • The transformer can also be used to swap X or Y values with the Z axis to produce a cross-section view of a dataset, such as a building model elevation.
  • The transformer can also be used as a tool for quality assurance purposes, where switching the data into a different plane causes spikes in the other axes, like this:

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.

Defining Values

There are several ways to define a value for use in a Transformer. The simplest is to simply type in a value or string, which can include functions of various types such as attribute references, math and string functions, and workspace parameters. There are a number of tools and shortcuts that can assist in constructing values, generally available from the drop-down context menu adjacent to the value field.

Dialog Options - Tables

Transformers with table-style parameters have additional tools for populating and manipulating values.
