I am looking for the best way to extract all islands of a polygon dataset.

 

 

Thank you very much!
Hi,

 

 

have you looked at the DonutHoleExtractor (http://docs.safe.com/fme/html/FME_Transformers/Default.htm#Transformers/donutholeextractor.htm)?

Hi David,

 

Thanks for your answer. By islands I mean real islands in middle of water without adjacent polygon. DonutHoleExtractor returns polygon that are completely within a bigger polygon.
Spatialrelator (intersect) on only polygons.

 

Test for related_candidates = 0
Very simple, thank you Gio
