The conception of soil classification generator (machine)

Abstract

The classifications of soils, which correspond the actual level of informational technologies, are able to provide the necessary clarity and conclusiveness of their conceptions, the implementation of formal methods for qualitative assessements and criteria of quality of estimations. The world soil science is now characterized by the absence of fundamental investigations on theory of classification, which is replaced by methods of data analysis. This paper suggests a new approach to creation of comprehensive classification as an attempt to fill a gap in this area. This approach is based on the idea of allotment classification (by Yu. A. Voronon). The purpose of classification is determined by the fixed system of the selected soil indices (specificities), which are organized as a graph of allotment classification. The number of objects in classification is determined by the number of selected specificities and their value grades. The edges of the graph reflect the descriptions of meaningful modes (types) of classification taxons. The recognition of new soils is made on the basis of similarity to them. It is the first time when the classification obtained analytical expression. Its equation allows us to code the vector of description of soils by a number, and as contrary, to restore the description on the basis of a code. That looks like an original database. Other classification and information materials may be moved into the forming classification space. For the purposes of supporting and realization of discussed approaches we created the special internet page: www.infosoil.ru.
