How to adjust distribution of points in PointCloudThinner?

Hi!

I got a shape of several million points, which I combine with the PointCloudCombiner.

I than use PointCloudThinner with the option to keep every 10th point.

In fact every 100th point would be enough, as it's a DTM of a very flat area, the problem is though that my result is a line of points where every single one is kept and than the space of 9 "lines" that are thinned out. I hope I could express myself properly here for you guys to understand.

Does anybody know a way to properly adjust the distribution of the points to be more evenly?

Greetings!

Hi @holysimpsons, how about once creating a DEM raster from the source points by the RasterDEMGenerator with preferable cell spacing? Then you can transform the raster into a point cloud by the PointCloudCombiner. It might be good to set PLANAR to the "Interpolation Method" in the RasterDEMGenerator.

Alternatively, PointCloudCombiner + PointCloudStatsRasterizer (FME Hub) + PointCloudCombiner might also be useful.

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