Help With LASClassifyPro

[Brian]

I have just completed using LASGroundPro and LASHeightPro on several tiled laz files.  When using the results from LASHeightPro as input to LASClassifyPro I get the attached error.  Has anyone experienced this error or anything similar?  If so what do I need to do to correct the problem?  I am using the latest licensed version of LASTools as a toolbox in ArcGIS 10.3.

Thanks,

Brian

Hello,

the option '-keep_overlap' was the culprit. This used to be an option in lasclassify that I had forgotten existed. Then I had reused this particular option name in the core LASlib library for the new overlap flag of the new LAS 1.4 point types. This was an option to keep those vegetation points that are overhanging a building classified as vegetation (by default they are set back to *unclassified*). This option was now (in the latest version 150701 of LAStools) renamed and is (more properly) called '-keep_overhang'. 

Regards,

Martin
