Abstract

Soil classification depends on the union of a series of chemical, physical, morphological and topographic factors. The understanding of the relationship among these characteristics aids in the knowledge of the landscape and, consequently, in the mapping. This way, the objective of this work was to verify the spatial correlation among soil classes and information about geology, topography and soils attributes. For this, it was generated a data bank with information about soil analysis, contour lines and geology. This information was crossed to verify the contribution of each one on soil map. The relief data were obtained from digital elevation model and the geology from an existing map of the area. It was concluded that there is high correlation among soil attributes and among them with geology and soil map showing that is possible to use these information to delineate soil classes.Key words:
