Hmm, you could use a dissolver to create two polygons out of the groups and then use a SpatialRelator/Clipper/SpatialFilter to pass a common arrtibute from the big polygons to the smaller ones. There's probably a better way but that would work

You can also use a reverse of @virtualcitymatt​ 's solution.

SpatialRelator/SpatialFilter to get the common attribute of the polygon and Dissolver with GroupBy on that attribute.

@caracadrian​ 

the features as connected to each one in Cascade A related to B , B related to C, ....

when you do the relator how could we get the common Attribute that related them all together?

If you use a spatialrelator to build a list of relationships for each feature, you can then use the custom transformer ListCombiner to assign groups

@ebygomm​  Hello How are you

is not given the expected result still we have the same group id for them

 

Have you verified that pano_name is unique?

In the ListCombiner I think you should also have pano_name selected under additional source attributes but I don't think that is the problem here

Are you able to share the data?

@ebygomm​ 

sure this is a sample of the data we are working on

Thanks

The list combiner works as expected for me on that sample data

Creates 3 groups (I've coloured them based on the group attribute). Group 0 contains 1 feature, Group 1 contains 21 features and Group 2 contains 30 features

@ebygomm​ 

Thanks for your help, I think I missed the setting

Again Big Thanks
