     105=== Classify using hyperspectral data or a DSM ===
     106
     107You can use the HYLIGHT tool als_classify to classify LAS files using a reference DSM or including hyperspectral files or a classification file.
     108Full instructions can be found in the [ manual] but some example commands:
     109
     110Fully classify points using a surface model and hyperspectral data:
     111{{{
     112als_classify --output classified_las  --hsclassification HS_class_mask.bsq  --vegheight --buildings  --alsfile unclassified_lidar_data.LAS  --refsurface my_reference_surface.bsq
     113}}}
     114
     115Classify noisy points against a surface model:
     116{{{
     117als_classify --output classified_las  --alsfile unclassified_lidar_data.LAS   --refsurface my_reference_surface.bsq
     118}}}
     119
     120==== using the wrapper ====
     121
     122To classify a directory of LAS files using a DSM only you can use the wrapper script classify_las_with_dem.py:
     123{{{
     124classify_las_with_dem.py --lidar unclassified_las_directory/ --dem dsm_in_same_projection_as_lidar.dem --output classified_las_directory/
