Click <img src="../../../Icon/Common/Delete.svg" alt="Lidar360 save" height="20" style="vertical-align:middle"/> to remove selected data, and click <img src="../../../Icon/Common/clear.svg" alt="Lidar360 brush" height="20" style="vertical-align:middle"/> to clear the imagery data list. After processing, the display mode of the point cloud data will automatically switch to RGB display (you can also click the <img src="../../../Icon/DisplayBy/displaycolor.svg" alt="Lidar360 displaycolor" height="20" style="vertical-align:middle"/> button on the toolbar to display the point cloud in RGB). File format: *.tif.
