Abstract: Natural landscape features, such as soil and vegetation, are represented by polygons in thematic maps. However, observations accomplished in the field demonstrated that these landscape elements present a continuous spatial variation that makes its depiction by exact lines rather incoherent. Such distortion in the conception of maps is yet a paradigm in Geosciences, Considering the need for a more realistic alternative for the cartographic representation of such themes, a computer routine based on fuzzy logic was here developed to convert crisp (Boolean) maps into fuzzy sets, using the PCRaster Environmental Modelling Language. Boolean maps of vegetation and soil types were decoded into fuzzy sets allowing the mathematical modeling of transition zones among geo-objects, where imprecision and/or uncertainties were dealt with consequently. The new digital fuzzy representations yielded in the process are tailored for modeling and spatial analysis of natural phenomena in Geographical Information Systems.
