Steps

1.Click Settings in the Tree Editor group on the Urban Forestry page. The following dialog box appears:

2.Set the required parameters and click OK.

Parameter Settings

• Ground Points Class: Applies to all functions in the Urban Forestry module except Segmentation. This class must be set when the ground is not normalized; otherwise, the functions cannot run.
• Parameters: Contains settings for individual-tree position, crown diameter calculation type, and DBH fitting method.
  • Crown Diameter Type: Provides Average Crown Diameter, Circle Fitting, and Ellipse Fitting.
    • Average: (North-South Crown Diameter + East-West Crown Diameter) / 2.
    • Circle: 2 * sqrt(Crown Projection Area / PI).
    • Ellipse: sqrt(North-South Crown Diameter * East-West Crown Diameter).
  • DBH Fit Method: Provides circle, ellipse, and cylinder fitting.
    • Circle: Fits a circle to the sliced point cloud at the configured DBH height.
    • Ellipse: Fits an ellipse to the sliced point cloud at the configured DBH height.
    • Cylinder: Fits a cylinder to the sliced point cloud at the configured DBH height.
  • DBH Height: Sets the DBH measurement height as required.
  • Minimum DBH: Trees with a DBH below this value are filtered during point cloud segmentation.
  • Maximum DBH: Trees with a DBH above this value are filtered during point cloud segmentation.
• Forest Render: Controls the visibility of DBH, CD, and Height in the 3D view.
  • DBH: A vector circle centered on the DBH fitting center, with DBH as its diameter.
  • CD: A vector circle centered on the DBH fitting center, with CD as its diameter.
  • Height: A vertical vector line using the seed point as its base and tree height as its length.

Note: The planar coordinates of the seed point are consistent with those of the DBH center.
