Description
v1.2.4 - minor bug fixes, one where in rare cases validation/decompression claims a zLAS file is invalid when it's actually fine, the other related to a carriage return potentially sent to a wrong window when the app is run from the command line.

The request for Esri to add direct support for LAZ files is at https://community.esri.com/ideas/13482-support-laz-format Please go and encourage Esri to incorporate this industry standard so those of us who need to work with both formats are not forced to maintain identical data in two repositories at once.
considered scrapping this project and simply working with rapidlasso to begin using LAZ instead of zLAS? https://rapidlasso.com/ ESRI should highly consider adding support for a laz dataset in ArcGIS
bad link in last post. the ability to add LAZ to a LAS dataset without converting means workflow simplification and easier data transfer. https://rapidlasso.com/
When decompressing a specific zlas file I got the error: The zlas file appears to be corrupt. I compressed the original LAS file and tried to decopress it but I got the same error again. What could be the problem?
Posts at http://blogs.esri.com/esri/arcgis/2014/01/10/esri-introduces-optimized-las/ and http://esriaustraliatechblog.wordpress.com/2014/02/19/compress-and-optimize-your-lidar-data-in-arcgis-10-2-1/ tout the direct use of zlas files in ArcGIS Desktop 10.2.1. My experience with 10.2.2 has been frustrating, as the "LAS to multipoint" tool recognizes and accepts the zlas file as input but then throws error 999999 "not a valid file" whether using the zlas or an las dataset where I added a zlas file. Not good! The "LAS to tin" tool only recognizes the las dataset and not not the zlas file. Please please include some instructions if you want this to catch on. I can't find anything on using zlas files directly in the desktop.
I too agree with bixb0012.
