The complete thesis in print form is available from the University Library. / A limitation of the geostatistical approach to spatial modelling of soil properties was redressed by adopting a continuum approach to soil classification. This involved the use of the fuzzy-c-means algorithm, to quantify pedons into intragrade and extragrade classes by minimization of the objective functional for the most "precise" classification. / Thesis (Ph.D.)--University of Adelaide, Dept. of Soil Science, 1991
