Identifying and reclassifying lidar point cloud

I’ve had good experiences in the past using LasTools auto classification (lasclassify - https://downloads.rapidlasso.de/html/lasclassify_README.html).

There are some custom transformers on the Hub for LasTools. However, LasTools is a licensed piece of software so this approach may well not work for your scenario

Unfortunately, I don’t have a license for those tools, so I won’t be able to give that a shot, but I really appreciate the input ​@hkingsbury! 

Hi ​@creinier thanks for your question! Are you able to provide a bit of sample data to test what solutions could work for you? Without seeing your data and not being able to use LAS Tools my only other suggestion would be to use some of the custom transformers on the FME Hub to help you classify your data, search for Point Cloud and there’s lots. ps. you can also edit custom transformers to fit your needs. 

If what you would like to share is sensitive or too large you could also submit a support ticket with this information and we’d be happy to help where we can! You can access your existing support tickets, or submit new requests here

Hi ​@evieatsafe - Thank you for the response! I apologize for the delayed response. Attached is a fgdb with a feature class named location_polygons that shows the location of the problem areas, and another feature class with the partial building footprints being generated (not all footprints are incomplete, just a few areas). The misclassified lidar point cloud can be downloaded from here, it was a bit too large to attach.

I’d like to just identify where actual building points are being misclassified so I can go back and fix the issue. I’ve been messing around with some of the different point cloud transformers but haven’t really made any progress. Any help is greatly appreciated! Thank you!
