Hi All,
I am having grid (red) polygons as shown below and I want to update Grid id to other polygons (black) when it covers maximum portion in that grid. Can any one suggest how it can be achieved in FME.
Thanks,
Ram.

Update attributes based on spatial relation

Hello again @kumarbangaram
Here is a suggestion for your requirements. I created some test data as I could get your test data to display correctly.
The Counters add the ID for each polygon in both Grid and Shapes.
The AreaOnAreaOverlayer intersects the two datasets.
The Tester removes the open space and any shapes that don't intersect.
The AreaCalculator then calculates the intersected areas.
The SpatialRelator then used to create the list
The ListSorter is used to sort based on area and then the first element in the list will be the one with the largest area. Hope this helps.

Hello @kumarbangaram
I would think an approach like the following:
1. Calculate the area of each of the black polygons
2. Intersect with red grid
3. Sort based on red id and black area
4. Add black id to red polygon
Do you have some sample data, and I will have a play in FME for you?
@deanhowell Thanks for reply.
Please find the Data.zip for your reference
Finally GridID attribute from Grid needs to transfer to GridID attribute of Parcel.
