Qualitative interpolation of spatial data

Abstract

This paper is on qualitative interpolation of spatial data. By considering the nature and magnitude of such data, they are very important in the spatial analysis process of natural phenomena. Qualitative data used in this research is related to soil color defined from morphological description of field-collected samples. The methodology was established through the followed steps: data acquisition; qualitative interpolation; phenomenon representation and visualization. The outcomes got from such procedure concerning the qualitative interpolation of the attribute color allow visualizing and representing the spatial variation of this morphological property.
