At one stage I remember looking at the average rate and variety of height change to make sure I am dealing with consistently changing features, presuming tree branches portray almost a random picture. | |

Added an update section to give a new info and to preclude irrelevant answers

| Jun 19, 2015 at 5:56 | comment | added | fatih_dur | Thanks @MichaelMiles-Stimson, in fact this is the best result that I got after Simplify feature tool varities and Aggregate Polygons seems irrelevant here. The result is (process-wise) pretty similar to the step (b) of Zhang/Knight methodology. | |
| Jun 19, 2015 at 5:33 | comment | added | Michael Stimson | Zhang may be credited with this but I can remember Michael Knight (at FUGRO at the time) was using this method in Microstation before then (2002-3).. try using Simplify Buildings or Aggregate Polygons. | |
