I have LAZ files that I unpacked with laszip.exe, then I ended up with LAS files.
These files showed no error when making a LAS dataset in ArcGIS. I used this dataset several times without ant issues.
But when trying to use
r.in.lidar in QGIS, I get this error:
ERROR: North must be north of South.
Since the files worked in ArcGIS, I am thinking this is a software or setup issue I have in QGIS.
I can't find that error message anywhere on the interweb.
