abstract = "Very few studies have been devoted to understanding the digital
terrain model (DTM) creation for Amazon forests. DTM has a special
and important role when airborne laser scanning is used to
estimate vegetation biomass. We examined the influence of pulse
density, spatial resolution, filter algorithms, vegetation density
and slope on the DTM quality. Three Amazonian forested areas were
surveyed with airborne laser scanning, and each original point
cloud was reduced targeting to 20, 15, 10, 8, 6, 4, 2, 1, 0.75,
0.5 and 0.25 pulses per square meter based on a random resampling
process. The DTM from resampled clouds was compared with the
reference DTM produced from the original LiDAR data by calculating
the deviation pixel by pixel and summarizing it through the root
mean square error (RMSE). The DTM from resampled clouds were also
evaluated considering the level of agreement with the reference
DTM. Our study showed a clear trade-off between the return density
and the horizontal resolution. Higher forest canopy density
demanded higher return density or lower DTM resolution.",
