AnchoredSnapper

Takes a series of features that match the input specification and performs snapping on the features that lie within the specified tolerance from other features that match the input specification. You can use this transformer to perform cleaning operations on data during a translation.

The difference between the AnchoredSnapper and the Snapper is that anchor features are considered to be accurate and consequently do not move.

Usage Notes

  • Any feature that undergoes dimensional collapse as a result of being snapped will be logged as "degenerate" and dropped. "Dimensional collapse" refers to a line or area that becomes a point, or an area that becomes a line.
  • A short cleanup step is performed after snapping. This step will remove duplicate points, and may create aggregates to preserve overlapping, directed segments.

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.
