This study is part of an integrated landscape analysis at Serra do Mar State Park – Picinguaba Nucleous, at Ubatuba, São Paulo State, based on the ecodynamics studies of Tricart (1977), the dynamic cartography of Journaux (1985) and the geosystemic approach of Bertrand and Bertrand (2002). Human impacts on natural landscapes were studied under three approach levels: terrain shape, processes and superficial deposits. The identification of anthroposoils is expected to bring indicators of man induced transformations of the landscape physiology and thus contribute to the understanding of Technogen. The applied methodology is based on remote sensing (Landsat 7-ETM+) to map actual land use and vegetation cover through image classification and on GIS geomorphological mapping with 30m grid DEM (refined from SRTM-90m data by kriging interpolation) and derived products, as slope angle, terrain curvature and others. The resulting layers are integrated with environmental variables towards the identification and the mapping of altered deposits. This methodology will be completed with the identification of deposits (Fanning and Fanning, 1998) and with the soil classification according to EMBRAPA (1999) and Curcio et al (2004). The study will be evaluated in field work and the final results shall further support a conservation plan for the area.
