Currently the LAS to multipoint tool only allows someone to filter LiDAR points by classification or return. But with the introduction of LAS version 1.4, LiDAR points can also be attributed with flags. But unfortunately this tool has not been updated to handle\filter by this flag attribute. The LAS to multipoint tools is still a valuable tool in the toolbox for dealing with LiDAR data, but it's inability to filter by flags limits its usefulness with modern LiDAR datasets. It would be useful if this tool could be updated to filter by flags.
