Hi all.

I'm struggling to get the LineOnLineOverlayer transformer to work. I'm working with MI tab files. I want to create a node at the crossing locations of an linear infrastructure data set 'A' with three other liner datasets 'B', 'C' and 'D'. The results I'm looking for is nodes at the crossing of A and B, A and C, A and D. The problem I have is not all intersections are being generated. The attached image shows an example of this. On the eastern side the blue dot represents an intersection between A and B. However, further to the west I would expect to see another two intersections but nothing has been generated.

The green polygon is one of may regions that is used to clip the poly line datasets to a manageable size before processing. The parent datasets are nationwide in geographic extent.

What have I missed? Do I need to deaggregate lines somewhere? (I've tried a few locations)

Thanks,

Michael
