I am working on a project creating building footprints from a lidar point cloud. However, the original lidar point cloud being used has some portions of buildings classified with “unassigned” values which has created incomplete building footprints. Are there any suggestions how I could identify these “unassigned” building values to fix the building footprint?

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
