<div>Dear All,</div>
<div> </div>
<div>I'm a bit fresh with all LiDAR data processing and analysis. </div>
<div> </div>
<div>I've got recently a bunch of LiDAR "las" format files, and their Vertical datum is ellipsoidal "WGS 84". The vertical datum is not defined within the las files, it was givin to me as a fact from the vendor.</div>
<div> </div>
<div>I need to convert these files to NAVD88 Vertical Datum, and I basically need to perform the following steps:</div>
<div> </div>
<div> 1- Define the vertical datum (WGS 84) ellipsoidal within the files</div>
<div>2- Transform to NAVD 88 </div>
<div> </div>
<div>I've got the "liblas" with "OSGeo w4", but I can not find a clear descriptions to the datums available or sample code regarding the above mentioned issue</div>
<div> </div>
<div>I would ask you kindly to help me with this, and would you please direct me to the right documentations?</div>
<div> </div>
<div>Thank you very much</div>
<div> </div>
<div>Ali</div>
