[en] One Tool Example

[en] Poly-Split has a One Tool Example. Visit Sample Workflows to learn how to access this and many other examples directly in Alteryx Designer.

[en] Use Poly-Split to split polygon or polyline objects into their component point, line, or region objects.

[en] This is a very specialized tool used for spatial layer development. A typical use of this tool is to disaggregate complex regions that may contain more than one polygon or to separate a polyline into its individual nodes.

[en] Configure the Tool

  1. [en] Choose the SpatialField object to split from the dropdown list.

  2. [en] Choose from the radio buttons which type of object the split will result in.

    • [en] Points: Splits regions into the points or nodes that make up that region. Each point becomes a record in the output.

    • [en] Regions: Splits regions into their individual component polygons. Each individual polygon becomes a record in the output.

    • [en] DetailedRegions: Splits regions into their individual component polygons and any holes in a polygon are also output as polygons.

[en] View the Output

[en] The Poly-Split tool appends two additional fields to the data stream:

  • [en] Split_SpatialObject: This is the resulting split polygon object.

  • [en] Split_IsHole: This is a boolean field, either true or false. True indicates the Split_SpatialObject is a hole. It may be useful to add a Filter tool after the Poly-Split with the expression not [Split_IsHole] to eliminate holes being attributed to records in the file. This field is only output when DetailedRegions is selected.
