+
+== Method ==
+
+=== classify_las.out ===
+
+This is a c++ utility written to do basic classification on LAS files. The current classification algorithms include:
+
+ * Isolated points - identify points as noise (classification 7) if there is no other point within x metres of it.
+ * Absolute elevation - identify points as noise (classification 7) if they are above or below a given elevation.
+
+A fence can be used to only classify points within a rectangular boundary. 
+
+'''Usage'''
+{{{
+ -lasfilein <LASFILENAME>    The LAS file to be imported and classified
+ -lasfileout <LASFILENAME>   The name of the output LAS file 
+
+optional flags
+
+ -isolated x                 Run the isolated points algorithm using a distance of x metres
+ -above x                    Run the absolute elevation algorithm classifying points with elevation above x metres
+ -below x                    Run the absolute elevation algorithm classifying points with elevation below x metres   
+
+ -fence minx miny maxx maxy  Use a fence whose bounds are given by minx,miny maxx,maxy   
+}}}   
+
+Currently only one method can be used per run of the software. This is due to be changed shortly.
