I have a polygon layer(shapefile) and points layer(from csv) and use "Points on Area Overlay" function to count how many points within each polygon.

But I don't know how to read the result. I have link the "area" output to a writer in shapefile format.

In the inspector, I found that all _overlaps fields are 0. I suspect there is something wrong.

_overlay or _match > than 0. Use the tester transformer.

Hi @yyj130, the PointOnAreaOverlayer could generate unexpected result if the coordinate system for the Point features was different from the one for the Area features. Make sure that those features have the same coordinate system.

Why not inspect features with Visual/Data Preview and Feature/Record Information before writing them into a destination dataset?

Thanks! I adjust the coordination system and it works!
