You are here: Geometric Operators > LineOnAreaOverlayer


Performs a line-on-area overlay. Each input line is split at any area boundaries it intersects.




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.

Generate List

Usage Notes

Each resulting piece receives the attributes of the area(s) it is contained in, and each containing area receives the attributes of the line. When attributes are merged between features, existing attributes are not replaced.  Therefore, if the lines 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.

Aggregates are not supported by this transformer.
