Land cover type and forest biomass assessment in the ColombianAmazon

摘要

Results of an analysis of AIRSAR data of the Colombian Amazon(province Guaviare) acquired during the 1993 AIRSAR South Americandeployment of NASA are discussed. Research is focused on the potentialof AIRSAR radar images to classify land cover types, such as primary andsecondary forest, recently cut forest, pasture, savanna and bush, takinginto account the influence of incidence angle and speckle level. Alsothe relation between backscatter and biomass level is studied. Very goodclassification results were obtained using combinations of two channels.High correlation between biomass and backscatter were found for manychannels. The use of (partial) polarimetry and circular polarizationsfurthers results
