The best tool to do a sequential split would be lassplit.exe ( README) but this requires licensing. Your best "free" option is the (somewhat unintuitively named) lasmerge.exe ( README) where you can do the splitting with this command, which splits the file every 500,000,000 points: lasmerge -i huge.las -o split0000.las -split 500000000.The ~Version and ~Well sections must appear in every LAS 3.0 file as the first and second sections respectively. Other sections are grouped by data type. Each group consists of two or three sections; a Parameter Data section (optional for all but Log data), a Column Definition section, and a Column Data section, in that order.2.
