Description
(First issue submission was here https://github.com/qgis/QGIS/issues/51193 - now moved to the right pace here)
When running e.g. lasinfo or las2las in cmd-line / OSGeo4W Shell the following error occurs:
error: Compression support not enabled in liblas configuration
Observations / Notes:
I think LASzip is missing in the packaging/compliling.
Running lasinfo or las2las in the cmd-line without params to show version header reveals:
lasinfo (libLAS 1.8.1 with GeoTIFF 1.4.2)
I expected:
lasinfo (libLAS 1.8.1 with GeoTIFF 1.4.2, LASzip n.n.n.)
What's also worth noting is that in bin (C:\Program Files\QGIS 3.22.13\bin), there is laszip3.dll but no laszip.dll. Renaming doesn't help.
Steps to reproduce the issue
Using QGIS 3.22.13 LTR or 3.28.1 (on Windows 11):
- Go to https://wheregroup.com/blog/details/visualisierung-und-manipulation-von-lidar-daten-mit-qgis-und-pdal/ and download the "LIDAR Testdaten aus OpeGeoData.NRW", unpack.
- Open OSGeo4W Shell and type "las2las" --> Check the header
- Paste the following into the command line:
lasinfo 3dm_32_510_5704_1_nw.laz
las2las 3dm_32_510_5704_1_nw.laz --output out.laz --extent "510100 5703500 510900 5704500"
