Abstract
A methodology for retrieval and mapping of spatial soil and. terrain d ata based on the SOTER approach has been developed for semi-ai:id Nige r. Remote sensing technics and detailed ground transect investigations are used, and the collected data are integrated into a SOTER database and a Geographic Information System. Transect selection, their realiz ation and the related problems with transect-based calculations are di scussed. The method permits estimations of soil type coverages, presen t land use and soil degradation at different scale levels. The signifi cant dynamics of soil redistribution are pointed out and attributed to present and past erosion events. (C) 1998 Academic Press.
