HI. I have a shapefile of Dissolved points and another shapefile of a polygon. Now I want to clip the polygon overlapping on the point file. Please note that the whole polygon area does not cover all the dissolved points.

I'm guessing you want to keep only the points inside the polygon?

Have you tried using the Clipper transformer?

Hi...Yes, I tried the clipper, but that is not giving me the output I want. Thanks anyways.

Can you perhaps give us some more details: what did you try and why isn't the output what you need? That way it's easier to help.

Hi @mukhtar_gf Do the points and polygons have the same coordinate system? Do they align if you view both in the Data Inspector - without background maps? You also might want to try the SpatialRelator, SpatialFilter, or PointOnAreaOverlayer.

Hi. Try to put reprojector at each reader to be sure that you're in the same coordinate system.

 

Then connect the polygon shape to a clippe clipper port and the point shape to the clipper port.

 

Don't forget to parameter attribute part of the clipper transformer as you wish.

 

And everything is gonna be alright ;)
