Soil-landscape correlations are used to produce and interpret digital soil maps. Thisstudy aimsto present a methodology for obtaining and preparing environmental covariates related to soil formation (lithology) and transformation (land use/land cover) to support digital soil mapping in Rio de Janeiro state, Brazil. Maps provided by the Geological Survey of Brazil and the MapBiomas Project were used. Lithology and land use/land cover classes, respectively, were merged according to class similarity and soil-landscape correlation. The derived maps have fewer classes and better correlation with soil formation and transformation, and thus, are ready to be used to produce and interpret soil spatial patterns in Rio de Janeiro state.
