[Liblas-devel] Ground Modeling with RAW LiDAR and libLAS

[Stuart Edwards]

GRASS GIS (open source) has several modules for processing raw LiDAR data and the ability to script your own classification routines.  LibLAS does a nice job of preprocessing (decoding) the LAS files so they can be input to GRASS as x,y,z or general ASCII format .......see:
