Hi,

I would like to know how to get the result from Spatial Relator without touching boundary between Parcel and Zones. Below attached image is my Workspace with Takashi's helping.

I want to find Planning Zone which is overlapping Parcel. But the result includes Planning Zone which is overlapping boundary between two as attached.

==============================================================================

Result for Parcel(SPI) 140A\\PP2159

  • Found Planning Zone : 622730 (It is not expected)

  • Found Planning Zone : 622729 (It is expected)

 

==============================================================================

Result for Parcel(SPI) A\\PS439634

  • Found Planning Zone : 598611 (It is not expected)

  • Found Planning Zone : 586792 (It is expected)

  • Found Planning Zone : 586224 (It is not expected)

I will much appreciate if I can have any idea to have the right result.

Thanks,

Jason Jung

Firstly make sure which spatial relation(s) you need to detect.
Does the test "Requestor Overlaps Supplier" match your intention correctly?
As far as I see your screenshots, I'm wondering that "Requestor is Within Supplier" is needed. Am I wrong?

Thanks your quick replaying. And let you know a parcel might overlap multiple zones. That reason is why I need to use "Overlaps" not "Within".

OK. You can choose both "Requestor Overlaps Supplier" and "Requestor is Within Supplier" (and also "Requestor Contains Supplier" if it's a possible situation) to detect your desired spatial relations. i.e. "Intersect" except "Touch".

 

However, I think you still need to make sure that there aren't small (invisible) overlaps on the adjacent boundaries.

Thanks Takashi, I would like to know how to shrink size of polygon because I am thinking for excluding small overlaps on the adjacent boundaries.

HI @jasonjungict, just set a negative value to the Buffer Amount parameter.
