3.If the observation point is selected incorrectly, you can click the "Repick Start Point" button in the visibility analysis settings window to choose a new observation point or click the "Repick End Point" button to choose a new endpoint for the observation range. Once the observation point and observation range are finalized, the next step is to select the point cloud vegetation type and point cloud building type in the settings window. You can also set the grid size and point cloud subsampling factor for the calculation. After setting all the parameters, click on the "Compute Visibility Area" button. Once the progress reaches 100%, the 3D view will display the computed visibility results. See the example below:
