+6Hi FME'rs
I would like to add land classifications stored in a polygon layer to a XYZ point cloud in an attempt to fudge an LAS-like dataset.
My approach so far was been to use to PointCloudCoercer to turn to XYZ to point, SpatialRelator to add the classification attribute from the polygon, then PointCloudCombiner to turn it back into a point cloud. As you can image, this is incredibly slow going.
Can anyone out there offer an alternative?

First question: why do you have to that?
Do you need all points in your point cloud? Thinning the cloud might make your process faster.
I don't have a full solution, but I would look into the PointCloudCombiner transformer. This transformer can make a pointcloud out of the polygon layer. That way you have a point cloud with your land classification. It might be easier to start from there?

+7Have you tried converting the vector to a raster and then using the PointCloudOnRasterComponentSetter transformer to carry the values across?
This works well if you are colorising a point cloud but should let you bring over either a colour value to represent a class or a class value as a component depending how you intend to visualise the resulting point cloud.
