From the profile ordinate data read at 1 μm intervals, a number of surface roughness parameters – centre line average, root-mean-square roughness, maximum height, maximum mean peak height, maximum mean depth, and absolute average asperity slope were calculated using a computer program.
A number of surface roughness parameters, viz., the center line average (CLA, Ra) and root mean square (RMS, Rq) roughness, maximum mean peak-to-valley height (Rtm), maximum mean peak height (Rpm), maximum mean depth (Rvm), and average asperity slope (Δa) were calculated.
In planted stands, a maximum mean top height of 29 m was recorded.
Lidar-derived maximum height, mean height and % canopy cover were compared to discrepancies between the CRM and Jenkins estimates (Fig. 5).
Several methods are used in practice for defuzzification, including the "centroid", "maximum", "mean of maxima", "height", and "modified height".
The quantitative analysis of root-mean-square roughness (Rq), cell volume, cell height, full width at half maximum (FWHM), and mean height of particles was also acquired by the above AFM software.
The maximum metal transfer peak height for each femoral head was calculated as the mean peak areal height (SRpm): the single maximum mean-to-peak height per each measurement location averaged over all scanned regions.
The resulting tree files were combined with LogCombiner 1.8.0 and the maximum clade credibility tree (mean height) was obtained with Tree-Annotator 1.8.0.
The best model using all 83 biomass plots included two lidar metrics, plot-level mean height and maximum height, with an r2 of 0.90 and root-mean-square error (RMSE) of 38.3 Mg/ha.
