Problem with SpatialFilter using intersects

I have a multiple base area that I am trying to use to add attributes to my parcel set.  I am using the intersects selector and it works for most of it, but I keep getting additional parcels selected that do not intersect the base.  Is there a way to get the program to not select these extraneous parcels?

I've always had better results using the SpatialRelator with TestFilter afterward when there are multiple bases.

Hi Joan,

 

 

'INTERSECTS' should be interpreted broadly, it includes 'EQUALS', 'TOUCHES', 'CROSSES', 'OVERLAPS', 'CONTAINS' and 'WITHIN'. I suppose one or more relationships in those are unsuitable for your purpose. You can see the strict definitions of spatial relationships here: http://docs.safe.com/fme/html/FME_Transformers/Default.htm#Transformers/spatialrelations.htm

Hi Joan,

 

 

I don't know your data, but maybe you have some multi part geometries that cause the strange results. So you can use the Deaggregator to resolve this. Afterward you can give the SpatialFilter another try...
