This transformer performs a line-on-line overlay. During the overlay, all input lines are intersected against each other and resultant line features are created and output. Intersection points are turned into point features that contain the merged list of attributes of the original intersected lines.
The Group By parameter specifies a series of attributes that must match on the features before they are considered for overlaying. This can be used to ensure that the overlay occurs only on certain groups of features. Click the browse button to select from a list of attributes.
The Overlap Count attribute holds the number of line features that intersected the resultant feature.
If the optional List Name is supplied, then all output POINTS will include a list containing attributes of each line that intersected at that point. If the List Name is supplied AND Separate Collinear Segments is set to No, then all output LINES will include a list containing attributes of each collinear line that was merged. If the optional List Name is supplied, AND Separate Collinear Segments is set to Yes, then no merging will occur and so output LINES will not include a list.
No: All collinear segments are reduced to one representative segment.
Yes: All collinear segments are output.
If the Advanced setting Geometry Handling is set to Enhanced in the workspace, arcs are accepted as lines; otherwise, arcs are not accepted lines.
