If, like me, you tried to process laz/las files (typically #lidar data) with #qgis under recent versions of ubuntu, you might have found out that ubuntu standard repos don't include pdal anymore.

I found a workaround by converting the files to copc using the conda version of pdal, then work with copc.

This morning I learned that there was a much better workaround, thanks to Martin Dobias on github: install qgis from the ubuntugis repos, as they include a pdal package.

https://github.com/qgis/QGIS/issues/53348

QGIS isn't built with PDAL · Issue #53348 · qgis/QGIS

What is the bug or the crash? Can't open LAZ files with QGIS. Steps to reproduce the issue Drag and drop a .laz file (this one was coming from IGN's LidarHD. Click here to download one of the files...

I wrote a technical guide on how you can create your own aerial imagery and 3D models of streets with the built in iPhone LiDAR sensor and open source tools in the OpenDroneMap package.

I've found you can attach your iPhone to your bike and generate LiDAR point clouds of the kerb and cycleway infrastructure if you go slow!

Somewhat aggrieved that I hadn't discovered the #QGIS multiple map canvas panels sooner. Makes interpreting #LiDAR that much easier. Some interesting linear features interacting with Bran/Brent Ditch around #Cambridge, totally absent from historic maps. #archaeology #gis #prehistory #medieval
