Abstract

In the context of global climate change, quantification of carbon stocks in forest stands has received more attention, mainly because forests play a key role in balancing the global carbon stock. Currently, existing methodologies for measuring carbon stocks in forests are constrained by budgetary issues and time, making it difficult to carry out a complete inventory within a short time. The combination of ALS ("Airborne Laser System") technologies and high-resolution multi-spectral aerial imagery has been used as an efficient and flexible alternative to estimate carbon stocks in forest stands, due to its accuracy and efficiency when compared to conventional methods. This study aims to evaluate the use of LIDAR ("Ligth Detection and Ranging") airborne laser technology (ALS) and high-resolution multi-spectral aerial imagery to estimate carbon stocks in the woody biomass of Eucalyptus plantations. The reality of the field will be set through biometric data collected from sample plots to act as independent variables to be estimated in regression models specially developed for fitting data generated by the LiDAR. The LiDAR variables will be obtained after processing the raw data generated by airborne sensors in specific software for this processing, such as FUSION 3.1, ArcGIS 9.3 and TNT Mips 7.2. For the study will be elaborated models correlating the carbon stocks obtained by conventional methods with variables obtained by airborne laser tecnology. The statistical analyzes will be implemented with the support of the software "R Project for Statistical Computing." (AU)
