I need to create a groundlevel polygon from a las file, including the height. No classification is added to the pointcloud.
It doesn't need to be precise; otherwise there would be generate to many polygons. A generalisation would be perfect.
For example I get a polygon where the height is between 17 and 17.50 meter; and another polygon where the height is between 17.50 and 18 meter
I tried serveral thing with surfacemodeller, surfacebuilder, creating buffers around the points. But I can't get my hands around this issue.
Hope someone as experience with such an analysis
