Editor

Steps

1.Click the Editor button and select the category and point cloud file to be edited. And then click the Start Edit button. The point cloud in the 3D window will then be displayed according to the selected individual tree type ID.

2.After starting the edit, an individual tree editing window will automatically pop up. In this window, you can add, delete, or modify individual trees.

3.In the 3D window, click the left mouse button to draw a hexagonal area to be edited. The points in this area will be displayed in the individual tree editing window. Area Editor settings allow you to switch the shape of the area, and support translation (WASD shortcut keys), rotation (QE shortcut keys), expansion, and scaling operations.

4.Click the Load Edit Region button in the individual tree editing window to load the point cloud of the area to be edited into memory for editing. If it's not loaded, editing is not supported.

4.If the selection frame was not positioned correctly and missed part of the tree, you can either redraw it or use the "Move"function in the 3D window to adjust the frame's position.

5.Click the pick Object button in the individual tree editing window to view the attribute information of the selected point, including three-dimensional coordinates, GPS time, intensity, RGB, object ID, etc.

6.Create Object: In the individual tree editing window, click the Create Object button and select the point cloud of the individual tree by frame to create the individual tree. At this time, the object ID of the points within the selected area will be set to a new object ID, and a new object record will be automatically added to the attribute table. If you want to finely edit the point cloud of an individual tree, you can use the "Set ID by Point Selection" and "Set ID by Frame Selection" operations.

7.Settings: In the individual tree editing window, click the Settings button. In the settings window, you can select to display only the points that need to be edited from two dimensions: category and individual tree ID, which can reduce the interference of background point clouds on the editing process and enhance the convenience of operation.

8.Zoom: If the point cloud is moved out of the current window display range and cannot be zoomed back during editing in the Single-Tree window, you can use the zoombutton to scale the selected area of the point cloud back into the current window view.

9.Hide Single Tree: In the single tree editing window, you can use the "Hide Single Tree" function to selectively hide trees that do not need editing. The hidden trees are linked to the visible trees in the settings window. To cancel the hiding, you can recheck the corresponding checkbox.

10.Delete Object: In the individual tree editing window, click the Delete Object button to delete an individual tree by point selection. The object ID of the points of this tree in the edit area will be reset to zero, and the object record in the attribute table will be deleted.
