Okay I thought this was going to be easy but I'm just not getting how to do this. I have a CSV that I have used to create points and from there I have made 10 mile buffers. I have another reader from SDE that is also a series of points. What I am trying to do is to find only the points that intersect the newly created buffers. I hope that is clear enough to understand..

I would connect the two features to a PointonAreaOverlayer (http://docs.safe.com/fme/html/FME_Desktop_Documentation/FME_Desktop_Help.htm#../Subsystems/FME_Transformers/Content/Transformers/pointonareaoverlayer.htm%3FTocPath%3DFME%2520Transformers%7CGeometric%2520Operators%7C_____18" target="_blank) transformer. The features you buffered would go the Area input port and the points you want to test go to the Point input port. 

 

 

Read up on the documentation if you want to get fancy with lists.

Hi,

 

Have u seen the SpatialFilter Transformer ???

 

This should help with your task

 

Feed in your datasets then set the operation mode eg

 

Intersect

 

Contains

 

Within

 

Overlap

 

etc

 

...........

 

Also check out the Help for this Transformer (Help btn in dialog box or Help panel when Transformer is selected) - really useful.

 

Help shows some really good pictures which explain what each operation mode does

 

............

 

Hope this helps
