Hi all.<br>
Lidar data in LAS format are increasingly widespread. Leaving aside all 3D frenzy, we<br>
would be interested in simply displaying them in QGIS, with their useful attributes<br>
(classification and intensity), either with a native driver or through an available<br>
library. All the licensing issues around libLAS/LSTools are a bit obscure to me, so I<br>
wonder if someone has already dealt with this.<br>
Any hint would be appreciated.<br></blockquote><div><br></div><div>Have you looked into PDAL [0][1]? It is already in OSGeo4W 32-bit, though apparently not in 64-bit yet [2][3]. On the Mac side, it is already available in the Homebrew package manager [4]. It appears to be BSD 3-Clause licensed.</div>
<div><br></div><div>Not entirely sure of its full API, but seems to be an ideal candidate for a Processing provider, yes?<br><br></div><div>While I am not a Lidar guru by any means, it looks like the JSON output from PDAL [5] is also an input for three.js [6], e.g. Qgis2threejs PyQGIS plugin. So that is fairly interesting... may be possible to load in a clipped .las file and visualize your map canvas on it? That would be very cool.<br>
