F. Graef et al., REMOTE-SENSING AND TRANSECT-BASED RETRIEVAL OF SPATIAL SOIL AND TERRAIN (SOTER) INFORMATION IN SEMIARID NIGER, Journal of arid environments, 39(4), 1998, pp. 631-644
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.
