Support ground object point measurement and wire point measurement. For the feature point model, the minimum horizontal distance, minimum vertical distance and minimum clearance distance from the small tower and power line can be measured in real time. For the wire point model, the minimum horizontal distance from the small tower, the minimum clearance distance from vegetation and the vertical distance to the ground can be measured in real time. Select the ranging type, click the left mouse button in the view window, select any ground object point/wire point, and obtain the minimum distance from the point to the small pole tower and power line.
