 === Point classification ===
 This is an important part of the QC procedure to remove noisy points. You can make a macro and save it to use again. See the LIDAR notes on how to classify the points. Once classified we may want to strip the points of a certain classification off the LAS file. (Example - low points). This can be done by selecting "Point -> Delete -> By point class". Then select the class you want to delete. You can use "Classify -> Add point to ground" to add individual/groups of points to a certain class by selecting them. This is important because your classification routine will most likely misclassify some points.

+To remove haze layers, you can classify by elevation selecting points, say, >200m off the ground and classifying them as low points. It is suggested that all points to be removed be classified as low points (even if they are high).
