Modify the colour of the filtered points so you can select for deletion by colour. Reform the DTM and repeat the filter for the number of iterations or, if 0.00, until less than 10% is removed by the last iteration. Max Volume Difference m³įilter small triangles by removing points where the resultant local difference in volume is small.įilter points where the total area of surrounding triangles is small. Select a DTM layer and a boundary Settings Max Triangle Grade %įilter out spikes and troughs by removing points where all surrounding triangles exceed the grade and all are either sloping away (a peak) or sloping toward the point (a trough).įilter large triangles of similar grade by removing points where surrounding triangles have a small difference in Common Side Grade.
