LineOnAreaOverlayer

From Fmepedia

LineOnAreaOverlayer is a Workbench Transformer.

Performs a line-on-area overlay.

Each input line is split at any area boundaries it intersects.

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 overlayed have attributes with the same name, then the values will not be transferred from one to the other. This can be worked around by renaming (AttributeRenamer), prefixing (AttributePrefixer), or removing (AttributeRemover or AttributeKeeper) attributes to avoid name collisions

The <overlap count attribute> added to output linear features holds the number of area features that they were inside of.

The <overlap count attribute> added to output area features holds the number of linear features that they contained.

Note that no intersections between area features are computed.
