You are here: Geometric Operators > PointOnLineOverlayer


Performs an overlay of points on lines. Each input line is split at its closest place to any point within the specified point tolerance.   




Attribute Accumulation

If attributes on the incoming and original feature share the same name, but are not geometry attributes that start with fme_, then they are deemed conflicted.

Note: On the PointOnLineOverlayer, Attribute Accumulation applies to the measures on a point in a similar way to how it applies to the attributes on a feature.

If measures on the point and line share the same name, then they are deemed conflicted.

The resolution of conflicted measures on points occurs in the same manner as the resolution of conflicted attributes on features. It is resolved according to the Accumulation Mode and Conflict Resolution values.

Usage Notes

  • Each resulting point receives the attributes of the point(s) it was paired with. When attributes are merged between features, existing attributes are not replaced. Therefore if the points and areas being overlaid have attributes with the same name, then the values will not be transferred from one to the other.  You can avoid this problem by renaming (AttributeRenamer), prefixing (AttributeExpressionRenamer), or removing (AttributeRemover) attributes to avoid name collisions.
  • Note that intersections between linear features are not computed.
  • Aggregates are not supported by this transformer.
  • Note that where Point geometries are expected as input, PointCloud geometries are not supported.

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.
