line on line overlay

Can you show us the data / what is not working? Would be great to understand more through an example and hopefully we can help.

It depends a little on how exactly your lines are overlapping, if they are intersecting or exactly laying on each other or are in close proximity to each other but it looks like they are overlapping.

You can try to use the SpatialRelator transformer and use your dataset as both the Requestor and Supplier. 

• Use "Requestor OGC-Touches Supplier" or "Requestor OGC-Intersects Supplier" or both to test
• And most importantly choose an ID attribute in your dataset in the “Attribute(s) that Must Differ” so that the same line doesn’t compare itself.

In LineOnLineOverlayer set in Attribute Accumulation

• List Name: OWNER
• Selected Attributes: OWNER

Send the output of this to ListHistogrammer.  Create Histogram for List: OWNER

Send the output of ListHistogrammer to Tester:  If _histogram{1}.value Attribute Has a Value =  Where a line segment that has at least 1 different OWNER.

Thank you for your replay, it  seems a logic answer however the lastpart i have understood it yet.

This what I have done, Still I have not got the result I want. Can you please look at it

Thank you for help!!

@hiyhelg , to be able to review, need to see the Transformer Parameter settings.

In FME, you can show this in a Transformer Pop-Out by selecting the Transformer, then pressing Ctrl-Shift-K

The correct Transformers are used.  The reason for no results is either

• Transformer Parameters not quite set correctly; or
• There are no overlaps between Lines with different owners, possibly because they are not exactly snapped to each other (Consider using a Snapper if this is the case)

Sample Data

Input to LineOnLineOverlayer , ListHistogrammer, Tester

Outputs the common line segment that has more than 1 Owner
