  • I need to assign a unique ID per named feature and need to distinguish when same named features are actually geometrically separate so I can assign them different IDs

So, I am working with a river linear dataset. I am assigning an ID to every river that all of the unique features of the river share. But, the issue that I am having is that there are some general names and one name is shared between 50 different streams (that contain 350 features). I located most of the using NodeValence and FeatureCounter where I group by name and valence 1. However, I cannot distinguish with 100% certainty which rivers are different even when they share the same name so that I may assign them different river IDs. I would need to include coordinates or similar. Any idea?

 

So, I am using the aggregator to aggregate by name, creating a list of unique IDs and appending the same ID to same named features. But the problem is that some same-named features are actually at different locations so I need to separate these and provide a separate river ID.

An update, I managed to get pretty good results with the NeighborhoodAgreggator, looking good so far.

@matija​  Would SpatialRelator give you the results you need? You could choose the spatial predicate that best matches your data, i.e. equals
