My las file had a spatial reference of "None." I tried to assign the CRS (in which data were collected) with the following command line:
las2las flightline_002.las --a_srs EPSG:32632 lasinfo --no-check flightline_002.las
Lasinfo still reports it as "None." See screenshot below, line 'Spatial Reference':
Those extent coordinates are UTM meters.
I am working through the examples on http://www.liblas.org/start.html#osx, with libLAS 1.7.0, GeoTIFF 1.4.0 GDAL 1.11.1, Mac OS 10.9.4. Any thoughts?
