Hi Narsimha, There will be a WKT (Well Known Text) string embedded in the LAS file, so you can just view using lasinfo then copy and paste into a text file. The format will be similar to this: http://spatialreference.org/ref/epsg/28355/ogcwkt/ <http://spatialreference.org/ref/epsg/28355/ogcwkt/> (you could also just use this file).
This is just a workaround for a bug, I had only tested with LAS 1.3 files so hadn’t tried with LAS files containing WKT strings. I’ll try and fix at some point so it will read the WKT string from the LAS file.
