How to create the group centers for each groups of points?

Assuming all your points have the same weight, you could use a coordinateExtractor to get the X,Y values of the points, then a StatisticsCalculator (analyze X|Y, group by on projectCode) to get the mean X|Y of each projectCode, then a VertexCreator on the Summary port to create a point at the center of mass.

 

 

EDIT:

 

Ignore the above, the easiest way would be aggregator (group by projectCode), followed by a CenterPointReplacer.

 

 

The documentation for the CenterPointReplacer needs to be updated so that it no longer says Non-area features are rejected.

Hi @ag,

 

Have you seen this previous Q&A; post? I think this sounds similar to what you are looking for.

 

You will want to use the Aggregator and Group By "projectCode" instead of the NeighborhoodAggregator to create the groups if you do not need a buffer distance around the points to be in a group.

 

And then use the CenterPointExtractor, then VertexCreator to replace the X/Y attributes with a point.

You could just use the centerPointReplacer rather than a CenterPointExtractor and VertexCreator.

 

 

Note that the documentation for the centerPointReplacer and CenterPointExtractor say that non area features will be rejected, which no longer seems true.

@AndreaAtSafe, Yes, the Q&A; post was similar. Thanks.

@jdh, yes aggregator followed by CenterPointReplacer works great. Thanks.
