+5Hi everybody,
I have a map with 'Layer A' (polygons district boundary) and 'Layer B' (lines roads).
I would like to add a field on my 'Layer B' table with the name of every district crossed by each road.
In this example, I would like my Road 1 attribute to tell me it crosses 'City A', 'City B', 'City C', and 'City D'. And my road 2 attribute to tell me it crosses ‘City A’.
Could you please show me how to make it? Thank you

I would suggest the SpatialRelator and Generate List of the cities. Then use the ListConcatenator to create the attribute that has all the city names for each road.

I suggest you to use te transformer LineOnAreaOverlayer and enable the List Attributes.

Hello
If I use LineOnAreaOverlayer, it will split multiple road based on polygon? Actually, I want to keep number records in Road.

Thank you so much, I did it :)
+5Hi everyody,
If I want to calculate length intersect with each city or scale length of each road in the each city if the road cross. I dont’ want to use LineOnOverlayArea, because it seperate line.
How can I do? Thank you

General Workflow
You need different transformers for this but the main steps are these ones:
You could include an attribute for example with the length distribution of the crossed cities in your final dataset:
'Length per city':
1500 m - city A - 1000 m - city B - 2000 m - city C - 100m - city D
I can supply you with a workspace when needed :)
