<br>
you can use the pointzip.exe tool, but that is mainly meant to "take<br>
the edge off" as it has been my experience that the terrestrial<br>
scanner folks are very GUI centric and these folks seem reluctant to<br>
enter the command-line world.<br>
<br>
instead of using pointzip.exe through the GUI you can also use<br>
<br>
laszip -i in.pts -ipts -o out.laz<br>
<br>
or<br>
<br>
laszip -i in.ptx -iptx -o out.laz<br>
<br>
and the extra PTS or PTX information will be stored in an additional<br>
VLR record so it could be recovered if needed (for the PTX it is<br>
likely needed if there are any values in the translation or rotation<br>
matrices)<br>
<br>
Is pointzip.exe being used much in the terrestrial world? I got a lot<br>
of feedback after release but it has died down since.<br>

PS: The web-site <a href="http://pointzip.org" target="_blank">http://pointzip.org</a> is really meant to house the<br>
"generic" compressor someday and I am still waiting vor Dave (USACE)<br>
or Paul (Elephant) to get back to me on that.<br>
