摘要: Abstract The objective was to identify landscape areas with different patterns of variability using a statistic protocol data magnetic susceptibility (MS) and soil color that are covariate attributes formation factors processes. studied area, 380 ha, is located in Northeast Sao Paulo State, Brazil. An amount 86 samples collected 30 m intervals on the transect. At transect sides, 150 were at 159 m (a point each 2.5 ha). First accuracy limits have been validated technique Split Moving Windows — SMW. identified extrapolated sides contours maps. MS peaks SMW, for both depths, presented correlation clay content (r = 0.7; P
