FORMAL APPROACHES TO THE EVALUATION OF NON-UNIQUENESS OF THE DELIMITATION OF GEOGRAPHICAL REGIONS
Abstract
Possible application of formal approaches for the evaluation of certainty of particular regions which are the result of flexible delimitation procedures is demonstrated. The scheme of the geoecological regions ofAfricacompiled through the complex multi-criteria analysis with both definite and flexible indicators was the object of study and certainty control. Regular grid cells of 0,5° 0,5° are the operational territorial units of study which are described by various parameters (in nominal or interval scales) from available thematic databases. A region is a territorial combination of adjacent grid cells characterized by similar values of region delimitation criteria. Three typical situations of the mathematical intersection of indicators for cell combinations (regions) are discussed which correspond to high, medium and low nonuniqueness of region delimitation. The results are interpreted in terms of the individual features of the regions; limitations of mathematical methods applied for their analysis are discussed. The most significant variables (criteria of the delimitation of regions) are determined. Possible application of the above-discussed methods for localization of the typical cores and peripheral parts of regions is described.
