+12Hi
I tried to join two linear datatset using this approach
I created (snipper) center point from one lines dataset and then I used the spatial relator to join the info to the 2 lines dataset but due to the mismatch of the coordsys of two datasets(I suppose) the center point doesn't touch the line (see picture)
I suppose that this is related to the tolerance during reprojection do you have same experience ?
thx
PS I solved creating a buffer for the center points

Getting points exactly on lines is hard to do because of floating point precision coordinates. (Coordinates in FME are not snapped to a grid.)
As an alternative for the buffering and spatial relator method you can use a PointOnLineOverlayer and use a Point Tolerance.
If you want to find out what a usable tolerance is, you can get a NeighborFinder to find the distances, but I think these are very small.
