From: The influence of LiDAR pulse density on the precision of inventory metrics in young unthinned Douglas-fir stands during initial and subsequent LiDAR acquisitions

Figure 4

Variation in root mean square error (RMSE) over a range of pulse densities when (a) H 70 , (b) H 10 and (c) H 95 are regressed against the corresponding LiDAR height metric at 10 pulses m−2. Closed circles denote values for the culled DTM while open circles denote values for the DTM held at a pulse density of 10 pulses m−2 throughout the culling process. The x-axis is displayed using a logarithmic scale with dotted lines vertically connecting values of 0.01, 0.1, 1 and 10 pulses m−2.
