#2388 closed enhancement (fixed)

GRASS 7.0 Beta 3 for windows r.in.lidar cannot read .laz files

Reported by: dnewcomb Owned by: grass-dev@…

CPU: x86-64 Platform: MSWindows 7

Description

The Windows binary for GRASS 7.0 beta 3 has not been compiled with the laszip library compiled into liblas. While it can read the LAS format well, it cannot read the compressed version ( LAZ) that is commonly used for download.

I feel it would be a worthwhile enhancement to add this capability to the windows binary.

The laszip library is licensed under the LGPL and is available at http://www.laszip.org/

That's strange, both OSGeo4W environments used for compilation and packaging contains libzip package. I checked native installer and it contains libzip.dll in extrabin dir. So no idea what could be missing.

Can you try to run "laszippertest" ?

it seems it's compiled with an old GDAL and an old LASzip.

is there any laszip test data around related to the NC sample data set?

just played around a bit with OSGeo4W-liblas (http://www.liblas.org/); although it claims to be compiled with LASzip 2.1.0, OSGeo4W-liblas can't read laz-files; e.g. lasinfo -i test.laz (test file from the lastools) crashes.

maybe open a ticket in http://trac.osgeo.org/osgeo4w/report ?
