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 3

Relationship between LiDAR pulse density and coefficient of determination (left side) and root mean square error (right side) for (a, d) mean top height, (b, e) volume and (c, f) mean diameter. 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.
