Abstract

Gamma-ray radioelements are a potential information source for soil mapping, since their abundance is related to soil geochemistry, specifically the chemical composition of parent materials and their weathering products resulting from geomorphic and pedogenic processes (IAEA 2003). Soils have been developed over sedimentation landscapes such as in alluvium and flood plain are uncertain due to the sedimentation process, which is difficult to characterize by field soil survey. Thailand has advantage of Airborne Gamma-ray Imagery (AGRI) covering whole country, for mineral survey but not yet for soil survey. Fuzzy classification method has been recommended as the potential techniue for digital soil mapping (McBratney et al. 2003).
