[Liblas-devel] Extracting specific classes with Python

[Howard Butler]

All,

A user requested that las2las have options to extract specific classes  
into a new file rather than using the elimination approach that it  
currently uses.  Unfortunately, the new release won't be out for a  
while, and because las2las tracks Martin's tools, I'm a bit hesitant  
to start adding lots of divergent options.  One thing libLAS has that  
LAStools doesn't is Python bindings, however, and this task is quite  
simple in Python.

The following command line invocation would use the above script to  
extract classifications 1 and 2 from the input.las file to the  
output.las file...

python grab_classes.py --input input.las --output output.las  -- 
classifications 1,2

Enjoy,

Howard
