“…Although no field measures were available for comparison at this study site, Coops et al (2007), working in a similar area with similar species, data, and methods for establishing mean plot height from LIDAR, found that LIDAR estimates of plot height were consistently lower than field-measured plot heights. As both the site index and modeled biomass estimates were generated from different data sources, they were expected to vary.…”

“…LIDAR data (either as a direct measure or as a data input for modeling) have been used to characterize forest attributes such as stand height (Naesset et al 2005), canopy structure (Ni-Meister et al 2001), crown closure (Lim et al 2003), biomass (Popescu 2007), and canopy volume (Lefsky et al 2005;Coops et al 2007;Heo et al 2008). Although LIDAR has largely been used for collecting highresolution geospatial data over vegetated areas, only in the last few years have natural resource scientists begun to use LIDAR for forest structure mapping and inventory purposes (Reutebuch et al 2003).…”

“…Segundo Forrester et al Devido à qualidade das informações produzidas, os sistemas ALS possuem inúmeras aplicações na área florestal, tais como: caracterização da estrutura da floresta (COOPS et al, 2007; LEFSKY et al, 1999; LIM et al, 2003), determinação do número de indivíduos (KAARTINEN et al, 2012;OLIVEIRA et al, 2012;VAUHKONEN et al, 2012) Outra abordagem que vem sendo utilizada é a dupla amostragem, que envolve a medição de duas variáveis, a principal ou de interesse, com maior custo e dificuldade de obtenção, e a secundária ou auxiliar, mais fácil e barata de se medir.…”

Esta dissertação visa explorar as possíveis contribuições do uso de dados ALS para a qualificação e quantificação de plantios clonais do gênero…”
