<p class="MsoNormal">Hi Martin,</p>
<p class="MsoNormal">great news: I’m craving for such an enhancement!</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Reading the description of the QEP I didn’t see great considerations about LAS &
<span class="st">LASlib.</span></p>
<p class="MsoNormal">From my experience, LAS format is almost a standard for ALS LiDAR data sharing and, even if LAZ is still not well known, the size can be shrinked to 1/10 thanks to it. It has a 2D index that can be easily created through the open source
tools of LAStools and it’s definitely well exploited using the streaming filters provided by LASlib (at least in IO operations). For what concerns the visualization,
<a href="https://github.com/Jean-Romain/PointCloudViewer">here</a> you can find how it has been solved for the R language (horrible for memory handling) making use of OpenGL.</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">BTW, I’m just a user and not a programmer…just curious why the above choices :)</p>
<p class="MsoNormal">All the best and keep up the great work!</p>

Hi all<br>
<br>
I have just published a draft of the proposal for introduction of<br>
point cloud visualization in QGIS:<br>
<a href="https://github.com/qgis/QGIS-Enhancement-Proposals/issues/194">https://github.com/qgis/QGIS-Enhancement-Proposals/issues/194</a><br>
<br>
Any feedback would be highly appreciated!<br>
<br>
We will be soon launching a crowdfunding campaign for the<br>
implementation - stay tuned!<br>
<br>
Regards<br>
Martin<br>
