Abstract


The main objective of the present paper was to develop amethodology using IKONOS II satellite images to estimate aboveground biomass and organic carbon content in Pinus taeda plantations.The methodology used, after field data collection, was to analyse the correlation matrix between satellite band values of reflectancy andvegetation indexes with above ground biomass and organic carboncontent, adjust and selection of regression equations to estimate aboveground biomass and organic carbon content as function of satellitevariables, such as reflectancy bands of MS-1, MS-2, MS-3, MS-4, MS-4MS-3 ratio, NDVI and SAVI , and quantification of the dependentvariables for the whole study area. The use of IKONOS II satellite imagesshowed satisfactory results, allowing to estimate above ground biomassand organic crbon content, needing for such fitting the appropriatemathematical models.
