I have two polyline datasets for rivers and streams. Dataset A and Dataset B. Dataset A is very old and the line work is not spatially accurate. Dataset B was created using more accurate methods.

I wish to compare Dataset A with Dataset B, keeping only the lines in Dataset B that intersect or are located near Dataset A. I do not wish to merge the attributes. I have tried nearest neighbor, but that merges the attributes. I have tried line on line overlay and intersector, but that doesn't appear to do what I want either (unless I am doing something wrong). The datasets do share a common attribute field (NAME), but due to the existence of duplicate names of streams within the data, matching by list does not work.

Any help would be appreciated.

Maybe try using the NeighborFinder with a group-by on NAME and setting a reasonable search radius?

I would try using the SpatialFilter transformer. First you could buffer dataset A to find "close by" features in dataset B.
