license issue".<br></blockquote><div><br></div><div>Oups. Found the thread. You are right. There was a discussion on this between you, Howard, and me over the Christmas days of 2014. I did not follow up as I was busy preparing myself to relocate to the Philippines for an over three months trip two days later. Once on the road criss-crossing Asia I never remembered it ... sorry about that oversight.</div><div><br></div><div>But in any case: FastAC has *absolutely* nothing to do with said "legal issues". I had an on-going conversation about all kinds of technical and legal details with ESRI and the name FastAC was never mentioned.</div><div><br></div><div>At the time there was no LASzip DLL. So to use LASzip you had to either take the code from here [1] and use it together with libLAS [2] or you had to write your own wrappers to take care of the (uncompressed) writing of the LAS header and the LASzip VLR. The only other option was to use it via LASlib [3] but that was at the time limited by language that did not allow the US nuke-labs to use the code. And it was distributed in one zip file [4] together with the commercial tools of rapidlasso. Working the way through understanding which parts of the how to use LASzip legal was what the legal department was doing. This was not about FastAC.</div><div><br></div><div>Here the original message from the 5th of February 2013 that resulted in my mention of "legal issues" in the history of LAS and "Optimized LAS" write-up:<br><br>"<span style="color:rgb(31,73,125);font-family:Calibri,sans-serif;font-size:11pt">I had started on this.
