I have a shapefile of 50,000 points and I would like to split this out and create polygons around groups of 500 points. Can anyone help with the easiest way to accomplish this?

From a shapefile of 50,000 points, the final output on this would be polygons that contain 500 points per polygon. Appreciate any guidance on the best way to do this.

Hi @gis_queen​ ,

Please have a look at the FME Hub transformer PointCloudDensityTiler. I think it may be able to what you want.

hmm it doesn't seem to like my filetype using a shapefile or file geodatabase. I have never worked with point cloud data types - should I just write this to some sort of point cloud file or try to?

You can use a pointCloudCombiner to convert your shapefile to a point cloud, no need to write out an interim format.
