Hi FME'er

I have created a shape file of crime data and I also have a boundary shape file of the neighborhood. I want to create a heat map to analyze which neighborhood has the most number of crimes for which i will be needing the count of total number of crimes that have taken place in that particular neighborhood. But i don't know how should I proceed to be able to do a spatial join and to calculate the count of crime points in each neighborhood polygon such that the output polygon will have an attribute field of the sum of the crime count.

Any help and guidance will be much appreciated. Thanks in advance

You can use a point on area overlayer for this. The overlap count attribute will report the number of points in each polygon

As @ebygomm says, the PointOnAreaOverlayer is the transformer for this. In case you want more information on this - and similar - techniques, I'd like to point you to some of our GIS tutorials here: https://knowledge.safe.com/articles/27998/tutorial-common-gis-operations.html

That tutorial covers a whole range of different spatial measurement and analysis techniques, and is very useful for scenarios like this.
