LineOnLineOverlayer

This transformer performs a line-on-line overlay. During the overlay, all input lines are intersected against each other and resultant line features are created and output. Intersection points are turned into point features that contain the merged list of attributes of the original intersected lines.

Attribute Accumulation

Usage Notes

  • When choosing to output only one segment for each collinear group, it may be difficult to predict which of the "original" geometries and attributes are preserved. In general, the features that arrive at the transformer FIRST will be the ones that form the separate segments. Use the FeatureHolder or Sorter transformers to change the sequence of features if this is important.
  • This transformer will preserve measures, based on the rules for the order of features described above.
  • Aggregates are not supported by this transformer.

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.
