Question

CAD to GIS Spatial Join: One to One , is it possible?


Hi,

I am trying to asses assets that are in CAD and not in GIS. Using the Spatial filter or the SpatialRelator i am getting results of one to many. I.e. the results are relating one candidate to many filters.

What transformer can i use that only spatial joins one candidate to only one filter?

 

Please help!

Hi, have you looked at the Matcher?

Hi,

Thank you for taking to the time to reply.

When i use matcher then i get no results - all go to "UnMatched"

Just to be sure: did you remove the Bufferer?

Thanks - i tired that and still get no matches. The two sources are not identical. They are two systems drawn individually that i am trying to compare to see what is missing from one source. From what i understand Matcher is where they are identical so this transformer isn't working either.

The Matcher has a parameter" Vector Tolerance", which allows two geometries to have spatial variation and still be considered a match.

It would depend on the differences between the two sources whether this would work.

I just noticed you are trying to compare lines. Maybe the LineOnLineRelator from FME Hub can help you out. Note that this transformer requires FME 2022.2.0.0 (Build 22765) or higher.
