    v14 v15  
    3737 -below x                    Run the absolute elevation algorithm classifying points with elevation below x metres   
    3838 -intensity x                Run the intensity based algorithm classifying points below a certain intensity level
    39  -cloud [a [m [t [i]]]]      Run the cloud search algorithm to classify cloud points below ground. This can be run using the default values or
    40                                 a = area over which to calculate the mean
    41                                 m = multiplier for distance away from mean eg mean - m*std deviation
    42                                 t = threshold to ignore classification eg areas with std deviations less than t are ignored
    43                                 i = intensity value threshold - ignore classifying points with intensity greater than i
     39 -cloud [a [m [t [i]]]]      Run the cloud search algorithm to classify cloud points below ground. This can be run using the default values
     40                             (shown in brackets) or values set on the command line
     41                                a = area over which to calculate the mean (500 metres)
     42                                m = multiplier for distance away from mean eg mean - m*std deviation (3.0)
     43                                t = threshold to ignore classification eg areas with std deviations less than t are ignored (4.0 metres)
     44                                i = intensity value threshold - ignore classifying points with intensity greater than i (10)
