[GRASS-user] Loading LPC data in GRASS

[Maris Nartiss]

Hello Andreas,
r.in.pdal still lacks metadata printing functionality and thus has not
been merged into the main branch yet. You can get the code from this
PR: https://github.com/OSGeo/grass/pull/1200

Let us know if there are any problems with r.in.pdal.
Best,
Māris.
