     10This is a c++ utility written to do basic classification on LAS files. The current classification algorithms include:
     11
     12 * Isolated points - identify points as noise (classification 7) if there is no other point within x metres of it.
     13 * Absolute elevation - identify points as noise (classification 7) if they are above or below a given elevation.
     14
     15A fence can be used to only classify points within a rectangular boundary.
     16
     17'''Usage'''
     18{{{
     19 -lasfilein <LASFILENAME>    The LAS file to be imported and classified
     20 -lasfileout <LASFILENAME>   The name of the output LAS file
     21
     22optional flags
     23
     24 -isolated x                 Run the isolated points algorithm using a distance of x metres
     25 -above x                    Run the absolute elevation algorithm classifying points with elevation above x metres
     26 -below x                    Run the absolute elevation algorithm classifying points with elevation below x metres   
     27
     28 -fence minx miny maxx maxy  Use a fence whose bounds are given by minx,miny maxx,maxy

     31Currently only one method can be used per run of the software. This is due to be changed shortly.
