Hi @kumarkannan1980,

You can see this solution in this case created here: Find gaps in Polygons

Thanks,

Hi,

I tried "Dissolver" ,"AreatoAreaoverlayer" to find gaps between polygons . It fails in some situation. The result is inconsistent. I tried "AreaAmalagamator" it is working fine but it is taking more time even for less volume of data. Any other method/transformer to find the gaps.

I noticed that Dissolver some times failed to dissolve if the gap of the polygon is more.

Create a bounding box (Creator or BoundingBoxAccumulator) for the complete area.

Then feed both the polygons and the box to the AreaonAreaOverlayer.

Use the Tester to test if _overlaps = 1, those are locations without a polygon (gaps).
