+3Hello,
I would like to decimate my point cloud to keep one point every meter for example.
I tried PointCloudSpatialThinner but i suggest it extrapolates the coordinates to fit the best to the original cloud point.
The problem I have is I can’t change z-coordinates. Optimally I’d like to decimate my point cloud only on the x and y coordinates.
Does someone have a solution ?
Best regards,
Gurvan

Hi
I believe that the PointCloudSpatialThinner transformer can get the job done with a few tweaks.
Since it’s a custom transformer, we can add the PointCloudSpatialThinner transformer to the canvas > right-click to Embed it > right-click again to Edit Embedded Transformer.
Now, we’re inside the custom transformer. Double-click the PointCloudExpressionEvaluator transformer > click on the row with the Z component > click the minus (-) button at the bottom > click OK.
With this Z component deleted, running the PointCloudSpatialThinner transformer should only decimate your point cloud based on the X and Y coordinates.
Let me know if this works for your dataset!

Hi
Thanks for your input. It worked partially but I learned I can edit custom transformer. After exploring others transformers I found PointCloudDupliucateRemover where it restores original XYZ after the point cloud is thinned. It does the job for me.
Have a good day !

I’m glad you were able to make it work for your workflow! Happy FME-ing!
