Fig. 7

An illustration of geometric inconsistencies among flight lines in ULS point clouds. a) A Silver birch from an easy plot, with 15-cm DBH. b) A Scots pine from an easy plot, with 23-cm DBH. c) A Scots pine from a difficult plot with 13-cm DBH. d) A Scots pine from a difficult plot with a DBH of 15 cm. The subfigures in middle zoom in to a one-meter-long section of the stems at +/− 50 cm of the breast-height at 1.3 m; the subfigures to the left show the horizontal profiles of 20-cm-thick slices of the stems at +/− 10 cm of the breast-height. The different colors (red/blue) show the flight lines of the points
