I have some questions about working with point clouds.

I’ve done a little work with them before in FME. Mostly coordinate reprojections, clipping, thinning, etc. Pretty basic stuff.

This time I have a slightly more complicated problem. I have an LAS data set that is not fully classified, there are no vegetation classifications.

I would like to use the LiDAR data to do some basic vegetation classification, resulting in shapefiles that I can use to classify areas that are vegetated.

As someone pretty inexperienced with FME, I’m not sure what the best sort of workbench is. I would love to see some examples and to experiment a bit with both of these problems.

I’ve built a few workflows but they don’t work!

We've had some really good success with LAS Tools - https://rapidlasso.com/lastools/lasclassify/ and embedding these system calls into FME.

 

We've also had a play around with filtering via color (RGB) and saturation (HSV) to extract asphalt/concrete. could apply something similar to vegetation

Thanks for the quick response. Will the learning curve be steep?

I didnt find it too bad, as long as your comfortable working with CMD/CLI then it its pretty straight forward.

The documentation is more example focused so there are some gaps
